横向多模效应对光子-光子门性能的影响

Transverse multi-mode effects on the performance of photon-photon gates

Bing He, Andrew MacRae, Yang Han, A. I. Lvovsky, Christoph Simon

摘要:

量子场的多模特性限制了在单个光子之间实现高保真量子门。到目前为止,这仅针对纵向自由度进行了研究。在这里,我们表明,由于横向自由度的影响显着影响量子门的性能。我们还讨论了潜在的解决方案,特别是分离的两个光子在横向方向。

英文摘要:

The multi-mode character of quantum fields imposes constraints on the implementation of high-fidelity quantum gates between individual photons. So far this has only been studied for the longitudinal degree of freedom. Here we show that effects due to the transverse degrees of freedom significantly affect quantum gate performance. We also discuss potential solutions, in particular separating the two photons in the transverse direction.
