Phys. Rev. A 65, 064301 (2002) [4 pages]Quantum computing in cavity QED with cold trapped ions by bichromatic radiationReceived 21 December 2001; published 30 May 2002 In the system with ions confined both in a linear trap and in a high-Q single mode cavity, we present a simple quantum computing scheme by means of lasers and quantized cavity field, based on a previous proposal with bichromatic radiation [Phys. Rev. Lett. 82, 1971 (1999)]. The controlled-NOT gate operation can be performed by only three operations and it is independent of motional states of ions. Experimental feasibility for achieving our scheme is discussed. © 2002 The American Physical Society URL:
