Yesterday Google shared a preview of Bristlecone, their new quantum processor. The purpose of the new gate-based superconducting system is to be a testbed for research into system error rates and scalability of their qubit technology, as well as applications in quantum simulation, optimization, and machine learning. This device uses the same scheme as their previous 9 qubit liner array technology for coupling, control, and readout, but is scaled to a square array of 72 qubits.



This is where I usually put my own insight or a witty remark, but since I only know what about 4 words mean in the entire release, I’ll just say “neat!”

We are cautiously optimistic that quantum supremacy can be achieved with Bristlecone, and feel that learning to build and operate devices at this level of performance is an exciting challenge! We look forward to sharing the results and allowing collaborators to run experiments in the future.
