Measurement of conditional phase shifts for quantum logic

Q. A. Turchette, C. J. Hood, W. Lange, H. Mabuchi, H. J. Kimble

摘要:

报道了在高精细度光学谐振腔中强耦合单原子双折射的测量结果,当腔内光子数远小于1时,观察到非线性相移。利用测量的条件相移实现量子逻辑通过量子相位门(QPG)的建议被认为是。在用于场变换的简单模型的上下文中,确定用于QPG的“真值表“的参数。

英文摘要:

Measurements of the birefringence of a single atom strongly coupled to a high-finesse optical resonator are reported, with nonlinear phase shifts observed for intracavity photon number much less than one. A proposal to utilize the measured conditional phase shifts for implementing quantum logic via a quantum-phase gate (QPG) is considered. Within the context of a simple model for the field transformation, the parameters of the "truth table" for the QPG are determined.
