Optical Nondestructive Controlled-NOT Gate without Entanglement Assisted
Year: 2006
Type: preprint
Abstract: We present and experimentally demonstrate a novel optical nondestructive controlled-NOT gate without entanglement assisted but only single photons instead. With much fewer measurements compared with quantum process tomography, we get a good estimation of the gate fidelity. The result shows a great improvement compared with previous experiments. Moreover, we also show that quantum parallelism is achieved in our gate and the performance of the gate can not be reproduced by local operations and classical communications.
