Implementation of quantum gates and preparation of entangled states in cavity QED with cold trapped ions
Mang Feng, Xiaoguang Wang · Journal of Optics B Quantum and Semiclassical Optics · 2002
We propose a scheme to perform basic gates of quantum computing and prepare entangled states in a system with cold trapped ions located in a single-mode optical cavity. General quantum computing can be done with both the motional state of the trapped ion and cavity state being qubits. We can also generate different kinds of entangled states in such a system without state reduction, and can transfer quantum states from an ion in one trap to an ion in another trap. The experimental requirements for achieving our scheme are discussed.
