Google 'Willow' quantum chip has solved a problem the best supercomputer would have taken a quadrillion times the age of the universe to crack
Google's new 105-qubit "Willow" quantum processor has surpassed a key milestone first proposed in 1995 — with errors now reducing exponentially as you scale up quantum computers.
Google scientists have created a new quantum processor that, in five minutes, cracked a problem that would have taken the world's best supercomputer 10 septillion years to solve. The breakthrough will allow quantum computers to become less error-prone the bigger they get, achieving a milestone that overcomes a decades-long obstacle.
Quantum computers are inherently "noisy," meaning that, without error-correction technologies, every one in 1,000 qubits — the fundamental building blocks of a quan computer — fails.
It also means coherence times (how long the qubits can remain in a superposition so they can process calculations in parallel) remain short. By contrast, every one in 1 billion billion bits fails in conventional computers.
This high error rate is one of the key barriers to scaling up these machines so they are good enough to perform far better than the fastest supercomputers. This is why research has centered on building quantum computers with better and less error-prone — not simply more — qubits.
Google says its new quantum processing unit (QPU), dubbed "Willow," is the first in the world to achieve results that are "below threshold" — a milestone outlined by computer scientist Peter Shor in a 1995 paper. The team outlined the technology in a study published Dec. 9 in the journal Nature. . .
