In this thesis, we are concerned with decoherence in quantum repeaters based on CNOT gate and a circuit QED system consisting of a charge qubit and two superconducting transmission line resonators (TLRs).

This paper describes interactions between the electric dipole field of water molecules confined within the hollow core of microtubules, quantized electromagnetic radiation fields based on cavity QED theory, and quantum computation based on the quantum mechanics principle.

In this paper,we depict the interactions between the electric dipole field of water molecules confined within the hollow core of microtubules and the quantized electromagnetic radiation field based on cavity QED theory,and quantum computation based on quantum mechanics principle.

We introduce the basic ideas of cavity QED, its recent progress and future prospects.

From the three aspects of quantum electrodynamics, quantum chromodynamics, and quantum flavordynamics, this paper explains that the vacuum is the special form of matter, the quantum field of ground state, but not the special state of matter.

In the first part, atoms are out of the dielectric slab, with the assumption of random orientation of the atomic dipole moment, the spontaneous emission rate of atoms is calculated by quantum electrodynamics, and results show to exhibit periodic damping oscillations when the .

Multi-particle Entanglement and Interference of Cavity Quantum Electrodynamics;

The article pointed out that carries out the schemes of physics in the quantum information processing to have: the Ion trap(Ion trap),the cavity quantum electrodynamics(Cavity QED),the nuclear magnetic resonance(NMR),the quantum dot(Quantum dot),according to superconductive system of the Josephson knot etc.

The cavity quantum electrodynamics (QED) method is adopted to discuss quantitatively the variation of spontaneous emission characteristic quantities versus the cavity structures in planar microcavity semiconductor lasers.
