Press release: New method of controlling qubits could advance quantum computers
Assistant Professor Yuhei Sekiguchi, Professor Kosaka and the YNU research team were able to demonstrate control of qubits by manipulating the electron spin through a combination of microwave manipulation and local optical shifting of transition frequencies of atoms and molecules, a process known as the Stark shift, using a nitrogen-vacancy center — a type of point defect — in a diamond.
 This research result has been published as “Optically addressable universal holonomic quantum gates on diamond spins” in Nature Photonics.
