Increasing Average Fidelity by Using Non-Maximally Entangled Resource in Teleportation of Superposed Coherent States
Quantum teleportation Superposed coherent state Entangled coherent state Average Fidelity
2011/8/17
Abstract: We consider the problem of teleporting superposed coherent state using non-maximally entangled coherent state as quantum channel and study the effect of entanglement over quality of teleport...
Cross-Kerr nonlinearity between continuous-mode coherent states and single photons
Cross-Kerr nonlinearity continuous-mode coherent states single photons
2013/7/3
Weak cross-Kerr nonlinearities between single photons and coherent states are the basis for many applications in quantum-information processing. These nonlinearities have so far mainly been discussed ...
We construct a class of coherent spin-network states that capture proprieties of curved space-times of the Friedmann-Lamaˆıtre-Robertson-Walker type on which they are peaked.

We develop an enhanced technique for characterizing quantum optical processes based on probing unknown quantum processes only with coherent states. Our method substantially improves the original propo...

We investigate quantum measurement strategies capable of discriminating two coherent states probabilistically with significantly smaller error probabilities than can be obtained using non- probabilist...
