'Supremacy' Achieved: Quantum Computer Notches Epic Milestone

Quantum supremacy has apparently arrived.


We have just entered the age of quantum supremacy, a new study suggests.

For the first time, a quantum computer has solved a problem that a traditional computer, for all practical purposes, cannot, researchers reported today (Oct. 23) in the journal Nature.

"A computation that would take 10,000 years on a classical supercomputer took 200 seconds on our quantum computer," study co-author Brooks Foxen, a graduate student researcher in physics at Google AI Quantum in Mountain View and the University of California, Santa Barbara, said in a statement.

"It is likely that the classical simulation time, currently estimated at 10,000 years, will be reduced by improved classical hardware and algorithms, but, since we are currently 1.5 trillion times faster, we feel comfortable laying claim to this achievement," Foxen added.

"This demonstration of quantum supremacy over today's leading classical algorithms on the world's fastest supercomputers is truly a remarkable achievement and a milestone for quantum computing," Oliver added. "It experimentally suggests that quantum computers represent a model of computing that is fundamentally different from that of classical computers. It also further combats criticisms about the controllability and viability of quantum computation in an extraordinarily large computational space (containing at least the 253 states used here)."
