Quantum logic gates using Stark-shifted Raman transitions in a cavity
(American Physical Society, 2004-06-04)
We present a scheme to realize the basic two-qubit logic gates such as quantum phase gate and controlled-NOT gate using a detuned optical cavity interacting with a three-level Raman system. We discuss the role of Stark ...
Transfer of an unknown quantum state, quantum networks, and memory
(American Physical Society, 2004-08-27)
We present a protocol for transfer of an unknown quantum state. The protocol is based on a two-mode cavity interacting dispersively in a sequential manner with three-level atoms in the Lambda configuration. We propose a ...
