Scientists in the US have introduced an ingenious new quantum chip architecture that significantly reduces disturbances caused by the signals used to control superconducting quantum bit (qubit) circuits. Led by Chuan Hong Liu and Robert McDermott of the University of Wisconsin, the team showed that the new multichip module (MCM) reduces gate errors by nearly a factor of 10 compared to earlier designs that used the same control system, making it a viable competitor to standard technologies.
