Cavity QED and Quantum Computation in the Strong Coupling Regime II : Two Atoms Case

In this paper we study the behavior of (laser–cooled) m–atoms trapped in a cavity interacting with a photon · · · Cavity QED · · · and attempt to solve the Schrödinger equation of this model in the strong coupling regime. In the case of m = 2 we construct Bell–Schrödinger cat states (in our terminology) and obtain with such bases some unitary transformations by making use of the rotating wave approximation under new resonance conditions containing the Bessel functions, which will be applied to construct important quantum logic gates in Quantum Computation. Moreover we propose in the case of m = 3 a crucial problem to solve on Quantum Computation.
