法拉第镜上的量子比特

A Qubit on the Faraday Mirror

F. De Martini, F. Sciarrino, V. Secondi

摘要:

在量子信息(QI)的上下文中,“法拉第筒”充当非通用的非门。因此,它的行为符合量子力学的原理。这个重要的结果,在QI社区最近的一些误解的核心,已经达到了一个彻底的实验研究的设备的属性,包括采用现代量子过程断层扫描。此外,由Mario Martinelli设计的“通用光学补偿”方法,在长距离量子密码学中常用,已经在理论和实验上进行了充分的研究。

英文摘要:

In the context of Quantum Information (QI) the ''Faraday Mirror'' acts as a non-universal NOT Gate. As such its behaviour complies with the principles of quantum mechanics. This non trivial result, at the core of some recent misinterpretations in the QI community, has been reached by a thorough experimental investigation of the properties of the device including the adoption of modern Quantum Process Tomography. In addition, the ''universal optical compensation'' method devised by Mario Martinelli, of common use in long distance quantum-cryptography, has been fully investigated theoretically and experimentally.
