Keiji Ono and colleagues from the RIKEN Center for Emergent Matter Science and the Toshiba Corporation in Japan, in collaboration with researchers from the United States, are investigating the properties of qubits produced by imperfections or defects in silicon MOSFETs. In particular, they are exploring their potential for developing quantum computing devices that are compatible with current manufacturing technologies.

"Companies like IBM and Google are developing quantum computers that use superconductors," explains Ono. "In contrast, we are attempting to develop a quantum computer based on the silicon manufacturing techniques currently used to make computers and smart phones. The advantage of this approach is that it can leverage existing industrial knowledge and technology."

After cooling a silicon MOSFET to 1.6 kelvin (−271.6 degrees Celsius), the researchers measured its electrical properties while applying a magnetic field and a microwave field.
