利用共振非线性光学实现高效光子计数和单光子产生

Efficient photon counting and single-photon generation using resonant nonlinear optics

Mattias Johnsson, Michael Fleischhauer

摘要:

研究了强非共振经典场和少光子共振量子场共同作用下原子双λ系统的行为。结果表明,该系统具有允许从多光子输入波包中提取单光子态的性质。此外,该系统还能够用作以任意高效率区分单光子波包和双光子波包的高效光电检测器。

英文摘要:

The behavior of an atomic double lambda system in the presence of a strong off-resonant classical field and a few-photon resonant quantum field is examined. It is shown that the system possesses properties that allow a single-photon state to be distilled from a multi-photon input wave packet. In addition, the system is also capable of functioning as an efficient photodetector discriminating between one- and two-photon wave packets with arbitrarily high efficiency.
