(ZDNet) Engineers from the University of New South Wales (UNSW) announced that they have measured the accuracy of silicon two-quantum bit (qubit) operations for the first time. There’s a big race internationally to build the first quantum computer and Australia is betting on silicon.
“All quantum computations can be made up of one-qubit operations and two-qubit operations — they’re the central building blocks of quantum computing,” UNSW Scientia Professor Andrew Dzurak said. “Once you’ve got those, you can perform any computation you want — but the accuracy of both operations needs to be very high.”
Research teams around the world have demonstrated two-qubit gates in silicon, but UNSW said until its breakthrough, the true accuracy of such a two-qubit gate was unknown.
