چکیده
In this work, we consider atomic spontaneous emission in a system consisting of two identical two-level atoms interacting dispersively with the quantized electromagnetic field in a high-Q cavity. We investigate the destructive effect of the atomic decay on the generation of maximally entangled states, following the proposal by Zheng S B and Guo G C [2000 Phys. Rev. Lett. 85 2392]. In particular, we analyze the fidelity of teleportation performed using such a noisy channel.

A new scheme for quantum teleportation is presented, in which the complete teleportation can be occurred even when an entangled state between Alice and Bob is not maximal.

I show a scheme which allows a perfect transfer of an unknown single-qubit atomic state from one atom to another by letting two atoms interact simultaneously with a cavity QED. During the interaction between atom and cavity, the cavity is only virtually excited and accordingly the scheme is insensitive to the cavity field states and cavity decay. Based on this scheme, a network for transfer of ...

First, I show a protocol to faithfully and deterministically teleport an arbitrary 2-qubit state from Alice to Bob. In this protocol two same Bell states are enough for use. Bob can recover the 2-qubit state by performing appropriate unitary operations conditioned on Alice’s two Bell-state measurement outcomes. Then I generalize the 2-qubit teleportation protocol to a N(N ≥ 3)-qubit teleportati...

Generation of arbitrary superposition of vacuum and one-photon states using quantum scissors device (QSD) is studied. The device allows the preparation of states by truncating an input coherent light. Optimum values of the intensity of the coherent light for the generation of any desired state using the experimentally feasible QSD scheme are found.
