多体束缚态诱导的无腔光子阻塞

Cavity-free Photon Blockade Induced by Many-body Bound States

Huaixiu Zheng, Daniel J. Gauthier, Harold U. Baranger

摘要:

对单个可移动量子的操纵是量子通信的一个关键目标;为了实现这一目标,开放系统中的非线性现象可以发挥关键作用。我们从理论上证明了在完全开放的一维波导与N型四能级系统(4LS)耦合时会发生各种强的量子非线性现象。我们重点研究了光子阻塞和在无腔条件下单光子态的产生。由于4LS介导的强光子-光子关联,出现了多体束缚态。这些束缚态导致光子阻塞,这可以产生亚泊松单光子源。

英文摘要:

The manipulation of individual, mobile quanta is a key goal of quantum communication; to achieve this, nonlinear phenomena in open systems can play a critical role. We show theoretically that a variety of strong quantum nonlinear phenomena occur in a completely open one-dimensional waveguide coupled to an N-type four-level system (4LS). We focus on photon blockade and the creation of single photon states in the absence of a cavity. Many-body bound states appear due to the strong photon-photon correlation mediated by the 4LS. These bound states cause photon blockade which can generate a sub-Poissonian single photon source.
