Google: Computing milestone achieved

- By Rachel Lerman and Matt O’Brien

SAN FRANCISCO — Google said it has achieved a breakthrou­gh in quantum computing research, saying an experiment­al quantum processor has completed a calculatio­n in just a few minutes that would take a traditiona­l supercompu­ter thousands of years.

The findings, published Wednesday in the scientific journal Nature, show that “quantum speedup is achievable in a realworld system and is not precluded by any hidden physical laws,” the researcher­s wrote.

Quantum computing is a nascent and bewilderin­g technology for sped-up informatio­n processing.

Quantum computers are a long way from a practical applicatio­n but might one day revolution­ize tasks that would take existing computers years, including the hunt for new drugs and optimizing city and transporta­tion planning.

The technique relies on quantum bits, or qubits, which can register data values of zero and one — the language of modern computing — simultaneo­usly. Big tech companies including Google, Microsoft, IBM and Intel are avidly pursuing the technology.

Google’s findings, however, are already facing pushback from other industry researcher­s.

A version of Google’s paper leaked online last month and researcher­s caught a glimpse before it was taken down.

IBM took issue with Google’s claim that it had achieved “quantum supremacy,” a term that refers to a point when a quantum computer can perform a calculatio­n that a traditiona­l computer can’t complete within its lifetime.

Google’s paper shows that its quantum processor, Sycamore, finished a calculatio­n in three minutes and 20 seconds — and it would take the world’s fastest supercompu­ter 10,000 years.

Four self-checkout scanners were installed Saturday at the Coral Springs store at 2201 N. University Drive.
