We propose a most simple and experimentally feasible scheme for teleporting unknown
atomic entangled states in driven cavity quantum electrodynamics (QED). In our
scheme, the joint Bell-state measurement (BSM) is not required, and the successful
probability can reach 1.0. Furthermore, the scheme is insensitive to the cavity
decay and the thermal field. 相似文献

Plasmon resonance coupling in strongly coupled gold nanotube arrays with structural defects 下载免费PDF全文
We theoretically investigate the transmission spectra and the field distributions with different defects in the gold nanotube arrays by using the finite-difference time-domain method.It is found that the optical properties of the nanotube arrays are strongly influenced by different defects.When there are no defects in the central nanotube,the values of peaks located at both sides of the photonic band gap have their maxima.Based on the distributions of electric field component E x and the total energy distribution of the electric and the magnetic field,we show that mainly a dipole field distribution is exhibited for the plasmon mode at the long-wavelength edge of the band gap but higher order modes of the composite are excited at the short-wavelength edge of the band gap.The plasmon resonant modes can also be controlled by introducing defects. 相似文献

Stationary entanglement between two spatially separated atoms driven by a coherent laser field 下载免费PDF全文
This paper studies quantum entanglement between two spatially
separated atoms driven by a coherent laser field in the dissipative
process of spontaneous emission. It is shown that the entanglement
strongly depends on the detuning of the laser frequency from atomic
transition frequency, the interatomic separation and the Rabi
frequency of the coherent laser field. A considerable amount of
steady state entanglement can be obtained near Δ=-α
(i.e., the dipole--dipole interaction and the detuning cancel out
mutually) for small atomic separation and large Rabi frequency of
the coherent laser field. 相似文献
