Implementation of a quantum $\sqrt{\rm_{swap}}$ gate for two distant atoms trapped in separate cavities
Lin Xiu, Rong‐Can Yang, Xiang Chen · International Journal of Quantum Information · 2015
We present a scheme to implement a quantum [Formula: see text] gate for two-atom trapped in distant cavities connected via an optical fiber. In the whole process, the atomic system, the cavity modes and the fiber are not excited ensuring that the operation is insensitive to atomic spontaneous emission, cavity decay and the fiber loss. This scheme is significant for distributed and scalable quantum computation.
