Unconditionally Secure Quantum Coin Tossing via Entanglement Swapping
Yong-Sheng Zhang, Chuan-Feng Li, Guang-Can Guo
An unconditionally secure quantum cion tossing protocol for two remote participants via entangled swapping is presented. The security of this protocol is guaranteed by the nonlocal…
Reply to the comment on `` Manipulating the frequency-entangled states by an acoustic-optical modulator''
B. -S Shi, Y. -K Jiang, G. -C Guo
In the paper [1], authors claim that the scheme for entanglement swapping using an acoustic-optical modulator [2] is flaw. In this reply, we show there is a trivial mistake in the…
Quantum authentication using entangled state
Yong-Sheng Zhang, Chuan-Feng Li, Guang-Can Guo
A scheme of quantum authentication is presented. Two parties share Einstein-Podolsky-Rosen (EPR) pairs previously as the authentication key which servers as encoder and decoder. Th…
Conditions for manipulation of a set of entangled pure states
Chuan-Wei Zhang, Chuan-Feng Li, Guang-Can Guo
We derive a sufficient condition for a set of pure states, each entangled in two remote -dimensional systems, to be transformable to -dimensional-subspace equivalent entangle…
Universal Quantum Entanglement Concentration Gate
Zi-Yang Wang, Chuan-Wei Zhang, Chuan-Feng Li +1
We construct a Universal Quantum Entanglement Concentration Gate (QEC-Gate). Special times operations of QEC-Gate can transform a pure 2-level bipartite entangled state to nearly m…
