An efficient two-bit quantum logic gate has been out of reach, until now.

An efficient two-bit quantum logic gate has been out of reach, until now.

Jung-Tsung Shen, associate professor in the Preston M. Green Department of Electrical & Systems Engineering, has developed a deterministic, high-fidelity two-bit quantum logic gate that takes advantage of a new form of light. This new logic gate is orders of magnitude more efficient than the current technology. “In the ideal case, the fidelity can be as high as 97%,” Shen said.
