Google has unveiled its new chip, Willow, which outperforms current computer benchmarks. Google says the chip solves a 30-year hurdle and advances quantum computing for commercial uses.
Sycamore is a transmon superconducting quantum processor created by Google's Artificial Intelligence division. [1] It has 53 qubits. [2] In 2019, Sycamore completed a task in 200 seconds that Google claimed, in a Nature paper, would take a state-of-the-art supercomputer 10,000 years to finish. Thus, Google claimed to have achieved quantum ...
Unlike your laptop, which uses bits to process information, quantum computers use something called qubits, short for quantum bits. Bits are binary digits, meaning they can only exist in one state ...

[5] [6] Hartmut Neven, founder and lead of Google Quantum AI, told the BBC that Willow would be used in practical applications, [4] and in the announcement blogpost expressed the belief that advanced AI will benefit from quantum computing. [1] Willow follows the release of Foxtail in 2017, Bristlecone in 2018, and Sycamore in 2019.
While regular computers can frequently err in problem-solving, Google claims Willow actually gets smarter as it uses more qubits, which are the units of computation in quantum computers.
In very simple terms the more useful a quantum computer is, the more qubits it has. However a major problem with the technology is that it is prone to errors - a tendency that has previously ...
This intermediate-scale is defined by the quantum volume, which is based on the moderate number of qubits and gate fidelity. The term NISQ was coined by John Preskill in 2018. [6] [2] According to Microsoft Azure Quantum's scheme, NISQ computation is considered level 1, the lowest of the quantum computing implementation levels. [7] [8]
