Google’s quantum chip solves ‘impossible’ problems in five minutes
Google has made a quantum computer chip that can solve a problem that would be impossible for the world’s most powerful traditional computers in just five minutes.
The international tech giant is putting billions of dollars into quantum computing, which experts believe will be able to herald advances in medicine, electrical vehicles and green energy. Qubits are made from tiny particles, such as the electrons of phosphorus atoms, which have “spin” and point magnetic north or south (the equivalent of zero and one), but also multiple directions in between, like a compass needle. Google has reported in a new paper, published on Monday in the journal Nature, that it has cracked this 20-year-long technical issue with a built-in guardrail that suppresses errors to a level low enough for the machine to be viable.
