远程量子比特中任意度的预示纠缠

Heralded Entanglement of Arbitrary Degree in Remote Qubits

U. Schilling, C. Thiel, E. Solano, T. Bastin, J. von Zanthier

摘要:

光子与两个具有λ能级结构的原子的非相干散射被用作基本的杨氏干涉仪,以预示任意程度的长寿命纠缠。纠缠度,作为衡量的并发,被发现是可调的两个容易获得的实验参数。将其中一个固定为某些值揭示了与马吕斯定律的类似。由于在实验实现的不确定性的纠缠度的变化的估计。

英文摘要:

Incoherent scattering of photons off two remote atoms with a Lambda-level structure is used as a basic Young-type interferometer to herald long-lived entanglement of an arbitrary degree. The degree of entanglement, as measured by the concurrence, is found to be tunable by two easily accessible experimental parameters. Fixing one of them to certain values unveils an analog to the Malus' law. An estimate of the variation in the degree of entanglement due to uncertainties in an experimental realization is given.
