    Description

    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. The potential applications include teleportation cryptography, super-dense coding of information and ultimately quantum computation. Central to these schemes is the usage of Einstein-Podolsky-Rosen (EPR) quantum entanglement. We propose to investigate these applications experimentally by using continuous-wave (CW) optics. The CW-EPR entanglement can be generated via a pair of optical parametric oscillators. The advantages of cw implementations are in the high photo detection efficiency and its compatibility with existing communication technology.
