Abstract

An idea for how to reconstruct the quantum state of a nonstationary single-photon wave packet absorbed in a macroscopic medium with inhomogeneously broadened lines is presented. An analytical treatment of the problem is performed and the requirements on the proposed scheme for complete recovery of the recorded nonstationary quantum state with a probability close to unity is described. The physical nature of the present scheme is also discussed.

摘要

提出了一种关于如何重构被吸收在具有非均匀展宽谱线的宏观介质中的非稳态单光子波包量子态的想法。对该问题进行了分析处理，并描述了对所提出的方案的要求，该方案要以接近1的概率完全恢复记录的非稳态量子态。还讨论了本方案的物理本质。
