Google achieves 'quantum supremacy'
LONDON • Alphabet's Google said it has built a computer that has reached "quantum supremacy", performing a computation in 200 seconds that would take the fastest supercomputers about 10,000 years.
The results of Google's tests, conducted using a quantum chip developed in-house, were published yesterday in the scientific journal Nature.
The idea behind quantum computing is to exponentially improve the processing speed and power of computers to simulate large systems, driving advances in physics, chemistry and other fields.
