Google creates quantum processor

Original layout of 5 cross-shaped transmons (Xmons) in a row

Google Quantum (Quantum AI), created last year, announced the inclusion of a group of physicists from the University of California, Santa Barbara, who recently developed a very promising design for quantum processors.

"With the participation of hardware developers from the University of California, we will now be able to implement in hardware and test new quantum optimization and quantum logic schemes based on recent theoretical discoveries in this area, as well as on our experience of using the D-Wave quantum computer architecture," in the message on the Quantum AI page on the social network.

Google will continue with NASA experiments with the architecture of D-Wave, but is going to try out the new quantum processors that were invented at the University of California. Their design provides, in particular, a new layout for the transmon qubit arrangement.

Control signals of all 5 qubits

Physicists from the University of California at Santa Barbara announced the development of a new architecture in April 2014. The architecture with elements of five cross-shaped superconducting transmons in a row is distinguished by simplicity and reliability. The number of errors does not exceed 1%, and if you reduce this figure by an order of magnitude, then the architecture can be used in commercial products.

The group of the University of California is headed by Professor John Martins, one of the world's best specialists in superconducting qubits. By the way, last year he gave a lecture at Google about his research (see video).
