Russian Scientists Use Supercomputer To Probe Limits of Google’s Quantum Processor
CPQM’s quantum information processing laboratory collaborated with the CDISE supercomputing team “Zhores” to simulate Google’s quantum processor. By reproducing noise-free data based on the same statistics as Google’s recent experiments, the team was able to point out the subtle effects lurking in Google’s data. This effect is called an accessibility defect and was discovered by the Skoltech team in past work. The numbers confirm that Google’s data is on the edge of the so-called density-dependent avalanche, which means that future experiments will require more quantum resources to perform quantum approximation optimization. The results were published in the leading journal “Quantum” in the field. From the early days of numerical calculations, quantum systems have become extremely difficult to simulate, although the exact reason is still an active subject of research. Nevertheless, classical computers clearly have inherent difficulties in simulating quantum systems, which prompted several researchers to change their views. Scientists such as Richard Feynman and Yuri Manin speculated in the early 1980s that the unknown components that seemed to make quantum computers difficult to simulate with classical computers could themselves be used as computing resources. For example, quantum processors should be good at simulating quantum systems because they are governed by the same basic principles. This early idea eventually led Google and other tech giants to create prototype versions of the long-awaited quantum processors. These modern devices are prone to errors, they can only execute the simplest quantum programs, and each calculation must be repeated many times to average the error to finally form an approximation. One of the most studied applications of these contemporary quantum processors is the quantum approximation optimization algorithm, or QAOA (pronounced “kyoo-ay-oh-AY”). In a series of dramatic experiments, Google used its processor to probe the performance of QAOA with 23 qubits and three adjustable program steps. In short, QAOA is a method designed to approximate the optimization problem of a hybrid setup composed of a classical computer and a quantum coprocessor. Prototype quantum processors such as Google’s Sycamore are currently limited to performing noisy and limited operations. Using hybrid settings, the hope is to alleviate some of these system limitations and still restore quantum behavior to take advantage of, making methods such as QAOA particularly attractive. Skoltech scientists have recently made a series of discoveries related to QAOA, for example, please refer to the article here. What stands out is the impact that fundamentally limits the applicability of QAOA. They show that the density of the optimization problem—that is, the ratio between its constraints and variables—is the main obstacle to achieving approximate solutions.

Tom Holland to star alongside Matt Damon in Christopher Nolan’s next, will juggle that with Spider-Man 4 in 2025
Tom Holland, last seen in Apple TV show The Crowded Room last year, has signed his next with Academy Award-winning filmmaker Christopher Nolan.
Tom Holland is going to have a very busy 2025. As per The Hollywood Reporter, the actor has signed Christopher Nolan’s next, which he will juggle the filming of with that of the long-awaited Spider-Man 4. (Also Read – Tom Holland shares why he left alcohol behind: ‘Struggling without booze…’)
Tom signs Nolan’s next
This will mark the first collaboration between Tom and Christopher. While details of his next directorial aren’t known yet, it’s most likely not to have a contemporary setting. It’ll be either set in the past like, his previous film Oppenheimer (2023), or in the future like Interstellar (2014). Matt Damon, who has worked with Christopher in both, has also come on board his next.
Christopher’s next will be co-produced by him and his wife Emma Thomas’ banner Syncopy Inc and Universal Pictures, as the two production houses will team up after the Academy Award-winning blockbuster Oppenheimer last year. Prior to Oppenheimer, Christopher collaborated mostly with Warner Bros before having a fallout post the debacle of Tenet (2020).
Warner Bros then went on to produce Greta Gerwig’s musical satire Barbie, which clashed with Oppenheimer at the box office and even outperformed it globally. Warner Bros offered Christopher a cheque for the fees he waived off for helming Tenet during the pandemic. While Christopher graciously accepted the belated remuneration, he still went on to pitch his next to Warner Bros.
Tom’s busy schedule
Tom didn’t have any release this year. His last outing was Todd Graff’s psychological thriller show The Crowded Room on Apple TV last year. He’ll juggle the filming of Christopher Nolan’s next and Spider-Man 4 in 2025. Tom has been playing the superhero ever since Russo Brothers’ 2016 blockbuster Captain America: Civil War. He’s slipped into the Peter Parker shoes post that for three standalone films and two Avengers movies. Spider-Man 4 will be helmed by Shang-Chi and the Legend of the Ten Rings director Destin Daniel Cretton.
As Tom’s girlfriend and co-star Zendaya will be busy filming Spider-Man 4 in 2025, she’ll reprise her role of Chani in Denis Villeneuve’s sci-fi spectacle Dune 3 only in 2026. Meanwhile, Tom is also likely to make an appearance as Spider-Man in Russo Brothers’ Avengers: Doomsday, which will go on floors in the spring of 2025.
