Google has refined and developed its 9-qubit linear array technology to create Bristlecone, a 72 qubit quantum processor. It presented Bristlecone at the annual American Physical Society meeting in Los Angeles. The new processor takes the attractive low error rate qualities of its predecessor, and it is hoped that using the new processor Google will be able to demonstrate quantum supremacy.

Bristlecone is a gate-based superconducting processor system. It was designed to preserve the underlying physics of Google's previous 9-qubit linear array technology with low error rates for readout (1 per cent), single-qubit gates (0.1 per cent) and two-qubit gates (0.6 per cent). As you can see above the processor uses a square array of 92 qubits (9 x 8).

So we're around 15 years from AES-128 being a complete joke and probably 20-25 years from AES-256 being a joke.

Who's ready for every encrypted file they've ever uploaded to the internet to be decrypted by the world's governments?
