无零差的脉冲压缩真空特性

Pulsed squeezed vacuum characterization without homodyning

J. Wenger, J. Fiurasek, R. Tualle-Brouri, N. J. Cerf, Ph. Grangier

摘要:

在实验上实现了直接光子探测,测量单模压缩真空态的压缩和纯度,而无需干涉零差探测。根据最近的理论建议[arXiv quant-ph/0311119],该装置只需要一个可调谐分束器和一个单光子探测器来完全表征所产生的高斯态。这个过程的实验实施进行了讨论,并与其他参考方法进行了比较。

英文摘要:

Direct photon detection is experimentally implemented to measure the squeezing and purity of a single-mode squeezed vacuum state without an interferometric homodyne detection. Following a recent theoretical proposal [arXiv quant-ph/0311119], the setup only requires a tunable beamsplitter and a single-photon detector to fully characterize the generated Gaussian states. The experimental implementation of this procedure is discussed and compared with other reference methods.
