The claim of D-Wave of Quantum Computer Domination is suspected

Quantum computing firm D-Wave says its equipment can solve problems that would be almost impossible for classical computers-but two different research groups have now suspected the claim.

As reported New scientist Last year, D-Wave published a pre-print that claimed its benefits Quantum computer transverse field calculations can calculate model problems-a quantum version of a mathematical container of how in changing states, such as a liquid to gas-would be impractically difficult to solve on a traditional computer.

That article has now been passed by a colleague review and published in the magazine. Science On March 12, but at the same time, researchers working on classical algorithms have shown that these problems are easily accessible to normal machines.

Dris Seals New York University and their colleagues say they have Similar calculation on a normal laptop in just two hoursUsing a region of mathematics called tensor network. These networks essentially reduce the amount of data, requiring a simulation, the computational power required to run is significantly cut.

Andrew king D-Wave says that it does nothing to change the company’s original claim. King says, “He did not do all the problems we did, he did not do all the sizes we did, they did not do all the observatories made by us, and they did not conduct all the simulation tests done by us.” “So this is a very big advance, these are great researchers … but it is nothing that refutes our claim of domination.”

King says that after hearing about the sales paper, he decided to run a big calculation of 3200 Quality – Quantum Bits, Quantum Computer Building Block – beyond the fake 54 beyond seals. He says it further displays quantum domination, although the results have not been published yet.

Sales call this reaction “slightly petty”, saying that their tensor approach can easily proceed. They say that the time to run the algorithm in proportion to the size of the problem, they say, so there is no need to test big problems. “If it really makes them (de-wave) super-wakes up, and then they would say ‘Okay, you guys’, we can do it,” says sales. “I don’t plan to do. I don’t see this point.”

separately, Linda Mauran And Gusepp Carleo In EPFL in Lozen, Switzerland, transverse field icing model problems say Quantum can be solved either without the need for complication – A major source of alleged benefits of quantum computers – or by imitating the minimum complication with a simple computer.

Carleo says the pair ran to publish their paper to match with D-Wave Science Publication, and he accepts that it only focuses on a kind of problem that is settled by the company and does not reach on the same scale. D-Wave paper suggests that such calculations will take up to 200 years on a powerful supercomputer, but he and Mauron and Mauron performed only four graphics processing units (GPU) in three days-calculating a quite a significant amount. He said, he says that within a week, it should be possible to cross the size of problems solved by D-Wave.

“The lesson to be learned is that if you say, ‘This is beyond classical simulation’, then there will be a classical simulation that will do it,” Calayo is called Carleo. “My suggestion, when they write these letters, avoid these claims, because they do not need them.”

In response, a D-Wave spokesperson rejected these calculations. “In our paper, we found this type of simulation that anyone is very easy to make a strong claim,” says the spokesperson. “While this paper seems an advance, it does not challenge our claims, whichever beeond-classical quantum simulation.”

If the results are confirmed to be reversed, this will not be the first time that quantum computers have been postponed as unbeatable, only to prove otherwise. In 2019, Google claimed that its sycamore quantum could perform computer calculations that would take the world’s most powerful classical supercomputer for 10,000 years to complete. But in 2022, researchers used 512 GPU to complete the work in about 15 hours, and in 2024 another team completed the same task in 14.22 seconds. Those classical speed-ups also trusted the tension network.

Alex Kisinjar The University of Oxford stated that D-Wave was one of the first start-ups to work on quantum computing, calling the first commercially available quantum computer in early 2011.

Questions about the amount of D-Wave are put on more or less bed at this point, but it can still be seen whether its equipment can actually solve problems that are impossible for regular machines. “I think, roughly, these days, they seem more respected than the old days when they were making these big claims and keeping all the details a little under the hood,” Kissinger says. “These days you can see a lot of detail about what their equipment really do.”
