My questions on QKD (II): CV protocol fiber and free space based QKD
2008-3-9 21:35
What are the key theoretical problems? Security proof of coherent state and squeezed state CV protocols for bare CVQKD system: What's the measure of security and so what's the absolute secure case (criterion)? How to provethe absolutesecurity of squeezed state andcoher ...

My question on the keys in QCI, slow light, light storage and optical buffer
2008-3-9 16:31
The following is the key for the optical buffer using QCI mechanism: bandwidth-delay-product (BDP): Hence, we need not only more delay, but alsobigger bandwidth of the QCI (EIT, CPO, or whatever) window. how about gaseous medium: too narrow bandwidth but the delay is very go ...

My questions on quantum entanglement (II): generation of entanglement and relate
2008-3-9 14:56
1) Some basics: So far, how many kninds of entanglement are there? I mean, for multipartite entangled states, we know both W state and GHZ state. I just want to know their properties. 2) How to generate photon-photon pair? How many methods are there available so far? At least for SSPDC method, w ...

My questions on quantum entanglement (I): measure and measurement of entanglemen
2008-3-9 14:52
The following questions are those related to quantum entanglement in my mind: 1) What's the general definition of the measure of entanglement? so, far, we have got to know several items, such as Schmidt number, von Neumann entropy (compare with Shannon entropy), and concurrence. 2)  ...
