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.

量子信息和通信是信息技术的一种新范式，它利用量子物理来改善当前信息传输和处理的速度，安全性和保真度的限制，扩展了现有的电子和光子器件。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Einstein-Podolsky-罗森（EPR）量子纠缠，这是通过一对光学参量振荡器产生的调查这些应用。与现有的单光子技术相比，CW的优势在于更好的检测效率、更宽的数据带宽以及与现有光子技术的兼容性。
