利用囚禁电子自旋和腔极化子共振实现全光普适量子计算

Towards All Optical, Universal Quantum Computation using Trapped Electron Spins and Cavity Polariton Resonance

Shruti Puri, Na Young Kim, Eisuke Abe, Yoshihisa Yamamoto

摘要:

我们提出了一个全光量子计算方案,利用捕获的电子自旋量子比特与光激发的微腔激子-极化激元的库仑交换相互作用。本文描述了一种单量子比特旋转,它与PRB 85,241403(R)(2012)中提出的双量子比特受控z门一起形成了一组通用逻辑门。通过优化泵浦脉冲参数,减小了由于腔寿命有限和旋转轴方向不正确而引起的误差。通过投影零差相位测量和初始化,我们的方案是一个有希望的候选者,物理实现的通用量子计算机。

英文摘要:

We propose an all optical quantum computation scheme, with trapped electron spin qubits, using their Coulomb exchange interaction with optically excited microcavity exciton-polaritons. This paper describes a single qubit rotation, which together with two-qubit controlled-z gate presented in PRB 85, 241403(R) (2012), form a set of universal logic gates. The errors due to finite cavity lifetime and incorrect orientation of the rotation axis are minimized by optimizing pump pulse parameters. With projective homodyne phase measurement and initialization, our scheme is a promising candidate for the physical realization of a universal quantum computer.
