多光子纠缠的按钮产生
Push button generation of multiphoton entanglement
摘要:
光子纠缠是线性光学量子计算方案、量子密码协议和量子力学基础测试的重要组成部分。在这里,我们描述了一个设置,允许产生的偏振纠缠的N-光子状态的需求。光子是通过将N个原子的纠缠态映射到自由辐射场而获得的,每个原子都被困在光学腔中。所需的初始状态可以通过执行后选择测量的集体发射从腔通过一个多端口分束器。
英文摘要:
Photon entanglement is an essential ingredient for linear optics quantum computing schemes, quantum cryptographic protocols and fundamental tests of quantum mechanics. Here we describe a setup that allows for the generation of polarisation-entangled N-photon states on demand. The photons are obtained by mapping the entangled state of N atoms, each of them trapped inside an optical cavity, onto the free radiation field. The required initial state can be prepared by performing postselective measurements on the collective emission from the cavities through a multiport beamsplitter.
