Quantum Photonics with continuous laser beams - travel award

量子信息与通信是信息技术的一种新范式，它利用量子物理学来改善当前在信息传输和处理的速度、安全性和保真度方面的限制，扩展了现有的电子和光子学设备。未来的应用将包括隐形传态、密码学和最终的量子计算。我们建议使用连续（CW）激光束和爱因斯坦-波多尔斯基-罗森（EPR）量子纠缠来研究这些应用，这是由一对光学参量振荡器产生的。与现有的单光子技术相比，连续波的优点是探测效率更高，数据带宽更宽，并且与现有的光子技术兼容。

Quantum information and communication is a new paradigm in information technology which utilises quantum physics to improve current limitations in speed, security and fidelity of information transmission and processing, extending the present Electronics and Photonics devices. Future applications will include teleportation, cryptography and ultimately quantum computation. We propose to investigate these applications using continuous (CW) laser beams and the Einstein-Podolsky-Rosen (EPR) quantum entanglement, which is generated via a pair of optical parametric oscillators. The advantage of CW over the established single photon technology is better detection efficiency, wider data bandwidth and a compatibility with existing photonics technology.
