Google Quantum Artificial Intelligence Laboratory today announced the new quantum calculator 'Bristlecone', Known as'Provides a very convincing proof of principle for building large quantum computers ' .
The processor already supports up to 72 qubits, Forming a matrix with each other, the error rate of data reading and logic operations is already quite low.
And if we can control the error rate of the quantum processor to a sufficiently low level, we can go beyond the traditional silicon computer to solve the explicit problem of computational science and realize the so-called Quantum supremacy.
To do this, you need a 49-qubit quantum processor with a circuit depth of over 40 and a double-qubit error rate of less than 0.5%.
Although no one can reach this point at present, however The 72 qubits for the Google Bristlecone processor have crossed a threshold, and Google is cautiously optimistic that it does have the power to do quantum hegemony.
However, Google also acknowledged that the quantum computer to go beyond today's silicon computer, Still need several iterations.
Google said, Bristlecone processor can be used as a test platform to study quantum error rate, quantum bit technology scalability, as well as quantum simulation optimization, machine learning.
Earlier this year, Intel has released a 49-qubit processor, is considered a milestone.
