Abnormal computer systems match Google’s quantum pc efficiency: Researchers

After Google mentioned that they had achieved what quantum computing researchers had hunted for years, a staff of Chinese language researchers now declare to have replicated the efficiency of Google’s Sycamore quantum pc utilizing conventional {hardware}.

In 2019, Google researchers claimed that they had handed a milestone often called quantum supremacy when their quantum pc Sycamore carried out in 200 seconds an abstruse calculation they mentioned would tie up a supercomputer for 10,000 years.

Now, scientists in China have finished the computation in just a few hours with atypical processors. A supercomputer, they are saying, might beat Sycamore outright.

“I feel they’re proper that if that they had entry to a sufficiently big supercomputer, they might have simulated the duty in a matter of seconds,” mentioned researcher Scott Aaronson, a pc scientist on the College of Texas, Austin.

The staff used a system comprised of 512 GPUs to finish the identical calculation developed by Google to exhibit it had handed the quantum supremacy milestone again in 2019.

The advance takes a little bit of the shine off Google’s declare, mentioned Greg Kuperberg, a mathematician on the College of California, Davis.

Nonetheless, the promise of quantum computing stays undimmed, the staff mentioned.

Sergio Boixo, principal scientist for Google Quantum AI, mentioned in an electronic mail the Google staff knew its edge may not maintain for very lengthy.

“In our 2019 paper, we mentioned that classical algorithms would enhance,” he mentioned. However, “we do not assume this classical strategy can sustain with quantum circuits in 2022 and past”.

The “drawback” Sycamore solved was designed to be exhausting for a traditional pc however as simple as potential for a quantum pc, which manipulates qubits that may be set to 0, 1 or any mixture of 0 and 1 on the similar time.
