D-Wave’s advantage2 Computer quantum chips
Kent Kallberg / D-Wave
D-Wave quantum computers say that his devices may solve problems that would be almost impossible for classic computers.
As reported New scientist Last yearD-Waw published his quantum advantage that the computer advantage could calculate the indirect area Problem problem problems – a quantum version of a mathematical approach Topic How it is played when changing the situationFor such a gas from a liquid – that would be impossible to fix it in a traditional computer.
This article has exceeded the peer review and published in the magazine Science March 12, but at the same time, researchers who work in classic algorithms have shown that these problems reach the ordinary machines.
Dries the sels At the University of New York and his colleagues say made similar calculations in a regular laptop in two hoursTensor networks using a math area called. These networks reduces the amount of data required by a simulation, reducing the computational power required to run.
Andrew King D-Waw says that doesn’t do anything to change the company’s original claim. “We didn’t have all the problems we did, we didn’t do all the sizes we did, they didn’t do all the observers we did, and they didn’t do all the simulation tests,” King says. “So in advance, they are great researchers … but it is not something that denies our suppression claim.”
The king says after listening to the Sels paper, he decided to make a larger calculation of 3200 ºC. He says, it shows more quantum dominance, even if the results are yet published.
Sels calls this answer to this “a little Petty”, saying that his voltage approach could easily be scale. The time to run the algorithm is linearly scaled in proportion to the size of the problem, so no need to test greater problems. “If (D-Wave) was very happy, and then they would say that” well, boy “could do,” says Sels. “I don’t intend. I don’t see the point.”
One by one, Linda Mauron and Giuseppe Carleo In Epfl in Lausanne, Switzerland, say that the indirect area is model problems It can be resolved without having quantum entertainment – A key source of supposed computers, or simulating a minimal connection with a regular computer.
Carleo says that the couple hurry to publish paper to join D-wave Science The publication, and acknowledged that the company only focuses on a type of problem planned and does not reach the same scale. D-Wave’s paper suggests that he would last 200 years in a powerful supercomputer, but Mauron made three days in three days, using a relatively modest number of computations. That said, it must be said within a week to exceed the size of the problems resolved by D-Wave.
“If you say a lesson to be learned,” beyond classical simulation “, then there will be a classical simulation,” Carleo says. “My suggestion, when they write these paper, it is avoiding these claims, as they do not need.”
In response, a D-Wave spokesman discarded these calculations. “In our paper, we found the simulations of this type to make hard claims,” he says spokesman. “This article seems to be a progress, it does not challenge our claims beyond quantum simulation.”
If the results confirm, it would not be the first quantum computer that were unique, otherwise to prove. In 2019, Google stated that Sycamore Quantum Computer can make calculations that would make up 10,000 most powerful classic supercomputers in the world. But 2022 researchers used 512 GPU Fill in the task for about 15 hoursand another group in 2024 The same task has been completed in 14.22 seconds. These classic speeds were also based on voltage networks.
Aleks Kissinger At Oxford University says it was one of the first starting points working in QUANTIC IT D-Wave, offering what is called First commercially available quantum computer at the beginning of 2011. But the company fucked in his early days Expert doubts whether his computers were really quantumor unnecessarily unnecessarily unnecessarily unnecessarily unnecessarily.
Questions about the Quantity of D-Wave At this point they have come to bed, but still, his devices must be seen whether ordinary machines can solve problems that are impossible. “I think in a wide way, it seems that greater sense are doing these great claims at once, and keeps all the details a little under the hood,” says Kissinger. “These days a lot of details can be seen what their devices do.”
