Google hails quantum supremacy

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 real-world system and is not precluded by any hidden physical laws,” the researchers wrote.

Quantum computing is a nascent and somewhat bewildering technology for vastly sped-up information processing. Quantum computers might one day revolutionize tasks that would take existing computers years.

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.
