Building a Quantum Computer From Off-the-Shelf Parts
IEEE Spectrum - January 2020

University of Chicago researchers develop stable and possibly scalable qubits by creating defects in commercial silicon wafers

A group of researchers at University of Chicago are pioneering a new technique for fabricating quantum bits by creating and manipulating small defects in commercially available silicon carbide wafers. The technique involves using an electron beam to create a deficiency in the wafer which behaves as a single electron spin. These electron structures can then be harnessed as possible quantum bits for quantum computation and communications.
