腔QED与强耦合区II的量子计算:两原子情形

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

Kazuyuki Fujii

摘要:

本文研究了囚禁在腔中的(激光冷却)m-原子与光子$...$相互作用的量子电动力学(QED)$...$的行为,并试图在强耦合区求解该模型的薛定谔方程。在m = 2的情况下,我们构造了Bell-Schr dinger猫态(我们的术语),并利用含有Bessel函数的新共振条件下的旋波近似,在这样的基上得到了一些幺正变换,这些变换将用于构造量子计算中重要的量子逻辑门.此外,我们提出了在m = 3的情况下,量子计算中要解决的一个关键问题。

英文摘要:

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 Schr{ö}dinger equation of this model in the strong coupling regime. In the case of m = 2 we construct Bell--Schr{\" o}dinger cat states (in our terminology) and obtain with such bases some unitary transformations by making use of the rotating wave approximation under new resonance conditionscontaining 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.
