Quantum Leap'S Raymond Lee is excited for fans to get more answers – and new questions – from the Season 2 finale.

During an exclusive interview with We weeklyLee, 37, admitted he was “not surprised” while reading the script for the second season finale.

“I know the capabilities of our writers. I know how good they are. It was just a matter of how much it would rock my socks off,” he explained. “I read that script and I immediately wish I could have sent a shotgun spray of texts because I'm trying to be as simultaneous as possible texting everyone who was responsible for writing the script about how impeccable their work was. “

Noting that viewers have plenty to look forward to, Lee added: “[The finale achieved] not just the loose ends of season 2, but also the entirety of season 1. And to also reach a level emotionally where we would feel satisfied as fans and as characters. I feel like there was no more tying the knot and that another dimension to another door was also possible if we continued. So I'm just so impressed. Not surprised, just incredibly impressed with everyone responsible for making that episode.

Season 2 introduced a three-year time jump that created more distance between Ben and the Quantum Leap team. Lee explained how the narrative decision helped shift the show into its next chapter.

“One of the main goals of Season 2 was to strip away the mythology a little bit, because we established that so well in the first season. The second season we really wanted to invest in the interpersonal relationships,” he explained. “We wanted to create a new obstacle for Ben and we wanted to see how it would all mix together.”

Lee highlighted how the second season pushed the story forward while creating “a lot of complications.”

Quantum Leap The surprises keep coming as Addison and Tom make plans to walk down the aisle immediately after their engagement.

In We weeklyIn the exclusive clip from the upcoming episode, which airs on Tuesday, February 6, Addison and Tom tell the Quantum Leap team about their decision.

“You're getting married. Today,” Jenn (Nanisa Lee) says to the couple as they admire Addison's (Caitlin Bassett) ring. The bride-to-be seems aware of the fast-paced timeline, noting, “We know it's a little sudden, but we would love for you all to be there.”

Tom (Peter Gadiot), meanwhile, is on the same page as Addison. “Not to mention, eloping saves us the hassle of planning a wedding,” he adds.

The greatest gift for us in 2024 would be fan-favorite couples like The Bear's Sydney and Carmy and Sweet Magnolias' Ty and Annie finally appearing on screen together. Since The Bear debuted in 2022, viewers and fans alike have been divided over whether the show will explore the potential romantic feelings between […]

Although Ian (Mason Alexander Park) is not happy about skipping wedding planning as that is their 'love language', Magic (Ernie Hudson) points out that the big day is “more about” Addison and Tom's love.

Addison also reminds the group that she has no positive memories of planning a wedding, adding, “Look, I planned a wedding once. Once was enough. This way it can be quiet, we can go to the courthouse around five o'clock and have a bite to eat.

At the end of the clip, Tom asks Addison if she regrets their choice.

“Are you sure I'm not rushing you?” he says before Addison responds, “If there's one thing I've learned from all of this, it's that you shouldn't wait to live.”

The surprise elopement comes shortly after Addison accepted Tom's proposal. The only problem seems to be the fact that her ex-fiance, Ben (Raymond Lee), is unaware of the latest developments in her personal life.

The former couple was mostly off for the entire second second after Ben realized he had been gone for three years. During his absence, Addison mourned Ben and eventually found love again with Tom. Since Ben is still jumping through time without a way to get back home, Addison chose to stay with Tom.

Ahead of Tuesday's episode, Bassett discussed how she rationalized Addison's relationship with Tom.

“I had always kind of broken it down where Addison and Ben were dreamers. They fell in love over a shared dream of this project and they were at a place in their lives where they just wanted to make the world a better place,” she shared exclusively. Us. “Who Addison became on the other side was when you realize that the world is going to break your heart and that you can't actually fix everything. That she accepted that and sat with it and [understanding] who she is after the dream dies a little. The kind of decisions you start making and then you start making a different kind of decisions.

'I told this man: I have a relationship with him, so I have that too. But now that other person comes up and I can't ignore that either, because there is a different kind of loyalty there.”

“In terms of the reception, we were all very happy to be there. We really liked the show. We had a lot of fun making it. I enjoyed making it,” she said Us about her experience filming the first season. “For me personally, I don’t read that much about critical feedback, message boards or things like that. You don’t have time when you’re making the show. So for me it felt like a perfect storm: just keep your head down, do your job, mind your business and stay out of trouble.

Quantum Leapa revival of the ’90s sci-fi series, follows Ben (Raymond Lee) after he makes a secret jump through time and gets lost in the past. With the help of his ex Addison (Caitlin Bassett) and the rest of the Quantum Leap team, Ben tries to figure out what caused him to change history.

Ben may come back to the present Us for a loop because it sounds too good to be true. According to Park, Ben’s potential return means the whole premise of Quantum Leap falls apart.

“If Ben comes back, we’ll be jobless,” Park joked. “Obviously, as characters, we all want to see a resolution to that storyline. We’ve been working for years and years – especially with the time jump – to bring this person back. I could probably say on behalf of all of us that as characters we want Ben back.

Park continued: “As an actor, I would like to do more episodes. So I’m sure [the writers room] has plans that I’m really excited about for all the different ways the show will continue from this point all the way to the season finale, which I think is really great.

Hudson, 77, meanwhile, is waiting to see how the plot twist plays out before getting his hopes up.

“It’s what we get into [with] trusting the producers and writing team. We all definitely want it when characters really want it [Ben to come back], but I also trust that they have looked further ahead. Like we said, we like the surprise of what comes next,” he explained Us. ‘And when Ben comes back, I’m sure it’s going to be very interesting. I’m excited about the possibility and I’m watching it all in one episode at a time. But the possibilities are all there.”

Lee also praised the writers for pushing the boundaries they themselves had created, adding: “It would change the format of the show quite drastically. But if it did happen, I’m sure our writers would find some really fun and interesting ways to develop that and maybe take another leap forward.

While the first half of season 2 aired, the cast is currently on set filming the remaining episodes. Without giving away any spoilers, the trio was able to tease where the story could go and how it will shape the future of the show.

“What’s really exciting for me is [the way] there are the characters, [but] there is still a great deal of it, [which] are the people behind the Pentagon. All these forces that make this possible that we actually have no control over,” Hudson pointed out possible threats. “They influence everything and how they come into play as we move forward is a mystery. But it is also very exciting. It’s not just up to us to just feel good about each other. There are other elements that really turn things upside down.”

Park has opted out of dropping any hints about how season 2 will play out, saying they know their “limits,” joking, “I’ll screw something up somehow.”

Lee, in turn, reminded viewers of the evolving character arcs and storylines.

“Season 2 has focused more on relationships. Between what’s going on with Ben and Addison together and separately [on an emotional level], as well as the rest of the team and what everyone is struggling with,” she noted. “It is a great opportunity for the audience to get to know other facets of these characters. Some of those things tend to build and we see some arcs of those things. But other than that I can’t reveal too much.”

“For me, I’d rather discover it as I go. But I think if some important things are going to happen, it’s nice to be aware of it because it affects everything that comes. [ahead of it],” Hudson said. “I don’t want to be completely naive about it, but I want to discover it as much as possible in the same way as the audience.”

Park said Us they would “get ridiculed a lot” on set for “not reading ahead” in their scripts.

“Narrisa makes it very difficult for me because of the level of uncertainty with which I may approach some things. But exploring is so much fun. It’s so fun to see what the writers come up with every week, especially because the show goes to some really wild places and it changes pretty drastically and really quickly,” they said. “I try not to get too attached to storylines or too attached to an idea of ​​what could happen, because chances are they’re going to throw a curveball at us anyway.”

Lee, meanwhile, enjoys checking in with her cast members to explain the big twists.

“Certainly, on more than one occasion I will [cast] thread, simply in capital letters after a script is released to us. It is exciting to be part of an ongoing series where big things are happening,” she noted. “I like to be surprised, but like Mason said, if it’s something directly related to our character, we get a heads up about it.

The actress concluded: “As for the twists and turns of things that happen with the program or during the jump, we just have one that I couldn’t control [about]. I only read it last night. It was insane. It’s going to be really exciting to deal with.”

Park joked that they were “selfishly excited” about their real-life partner Alice Kremelberg‘s presence on the show because of the glimpses fans have gotten into their character Ian’s personal life.

“We’ve been wanting to do something together for a long time, so it was so fun to find out that the writers actually wanted to make it happen at some point,” they shared. “It was something we literally talked about during the pilot. So that was really cool to see it come to fruition and be more than just a one-off, one-off experience. It’s nice for Ian to have someone who can respond to that.

Hudson concluded by pointing out how Quantum Leap elevates its guest stars.

It’s not just a performance, the episodes are really written in a way to really show what they’re doing,” he said. “Stan Shaw, who has been a friend of mine for years, to see him come out and have fun, that was really important to me.

Quantum computers today are small in computational size – the chip in your smartphone contains billions of transistors, while the most powerful quantum computer contains a few hundred of the quantum equivalent of a transistor. They are also unreliable. If you do the same calculation over and over, they will most likely produce different answers each time.

But with their inherent ability to consider many possibilities at once, quantum computers don’t need to be very large to tackle certain thorny computational problems. would lead to reliable, useful answers.

“What IBM showed here is really an amazingly important step in that direction to make progress toward serious quantum algorithmic design,” said Dorit Aharonov, a professor of computer science at the Hebrew University of Jerusalem, who was not involved in the project. research.

While researchers at Google claimed in 2019 that they had achieved “quantum supremacy” — a task performed much faster on a quantum computer than on a conventional computer — IBM researchers say they’ve achieved something new and more useful, albeit with a more humble name.

“We’re entering this phase of quantum computing that I call utility,” said Jay Gambetta, vice president of IBM Quantum. “The Age of Utility.”

A team of IBM scientists working for Dr. Gambetta described their results in a paper published Wednesday in the journal Nature.

Contemporary computers are called digital or classic because they deal with bits of information that are 1 or 0, on or off. A quantum computer performs calculations on quantum bits, or qubits, that capture a more complex state of information. Just as a thought experiment by physicist Erwin Schrödinger postulated that a cat could be in a quantum state that is both dead and alive, a qubit can be both 1 and 0 at the same time.

As a result, quantum computers can make many calculations at once, while digital computers have to perform each calculation separately. By speeding up computation, quantum computers could potentially solve large, complex problems in fields like chemistry and materials science that are out of reach today. Quantum computers can also have a dark side, threatening privacy through algorithms that break the safeguards used for passwords and encrypted communications.

When Google researchers claimed supremacy in 2019, they said their quantum computer performed a calculation in 3 minutes and 20 seconds that would take about 10,000 years on a state-of-the-art conventional supercomputer.

But some other researchers, including those from IBM, ignored the claim and said the problem was fabricated. “Google’s experiment, as impressive as it was, and it was really impressive, does something that is of no interest to any application,” said Dr. Aharonov, who also serves as Chief Strategy Officer of Qedma, a quantum computing company.

The Google calculation also turned out to be less impressive than it first appeared. A team of Chinese researchers was able to perform the same calculation on a non-quantum supercomputer in just over five minutesmuch faster than the 10,000 years the Google team estimated.

The IBM researchers in the new study performed a different task, one that interests physicists. They used a quantum processor with 127 qubits to simulate the behavior of 127 atomic-scale bar magnets — small enough to be governed by the ghostly rules of quantum mechanics — in a magnetic field. That’s a simple system known as the Ising Model, which is often used to study magnetism.

This problem is too complex for even the largest, fastest supercomputers to compute a precise answer.

On the quantum computer, the calculation took less than a thousandth of a second. Each quantum computation was unreliable – fluctuations of quantum noise inevitably creep in and cause errors – but each computation was fast, so it could be performed repeatedly.

In fact, many of the calculations were deliberately added extra noise, making the answers even more unreliable. But by varying the amount of noise, the researchers were able to pinpoint the specifics of the noise and its effects at each step of the calculation.

“We can amplify the noise very precisely, and then we can repeat that same circuit,” said Abhinav Kandala, the manager of quantum capabilities and demonstrations at IBM Quantum and an author of the Nature paper. “And once we have the results of these different noise levels, we can extrapolate what the result would have been if there had been no noise.”

Essentially, the researchers were able to subtract the effects of noise from the unreliable quantum calculations, a process they call error mitigation.

“You have to get around that by thinking of really clever ways to reduce the noise,” said Dr. Aaronov. “And this is what they do.”

All told, the computer ran the calculation 600,000 times, resulting in an answer for the overall magnetization produced by the 127 bar magnets.

But how good was the answer?

For help, the IBM team turned to physicists at the University of California, Berkeley. While an Ising model with 127 bar magnets is too large, with far too many possible configurations, to fit into a conventional computer, classical algorithms can yield approximate answers, a technique similar to how compression in JPEG images throws out less crucial data in order to size of the file while preserving most of the details of the image.

Michael Zaletel, a physics professor at Berkeley and an author of the Nature paper, said that when he started working with IBM, he thought his classical algorithms would outperform the quantum algorithms.

“It turned out a little differently than I expected,” said Dr. Zaletel.

Certain configurations of the Ising model can be solved exactly, and both classical and quantum algorithms agreed on the simpler examples. For more complex but solvable cases, the quantum and classical algorithms produced different answers, and it was the quantum algorithm that was correct.

So for other cases where the quantum and classical calculations diverged and exact solutions are not known, “there is reason to believe that the quantum result is more accurate,” said Sajant Anand, a graduate student at Berkeley who did much of the work. to the classical approaches.

It is not clear that quantum computing is indisputably the winner over classical techniques for the Ising model.

Mr. Anand is currently trying to implement a version of error mitigation for the classical algorithm, and it is possible that it will match or exceed the performance of the quantum computations.

“It’s not clear they’ve achieved quantum supremacy here,” said Dr. Zaletel.

In the long run, quantum scientists expect that a different approach, error correction, can detect and correct computational errors, and that will open the door for quantum computers to move forward for many applications.

Error correction is already used in conventional computing and data transmission to fix corruptions. But for quantum computers, error correction is likely years away, requiring better processors that can handle many more qubits.

Error mitigation, according to the IBM scientists, is an intermediate solution that can now be used for increasingly complex problems outside of the Ising model.

“This is one of the simplest science problems out there,” said Dr. Gambetta. “So it’s a good one to start with. But now the question is, how do you generalize it and move on to more interesting science problems?”

Think of discovering the properties of exotic materials, accelerating the discovery of medicines and modeling fusion reactions.
