چکیده

We show how the state of an atom trapped in a cavity can be teleported to an atom trapped in a distant cavity simply by detecting photon decays from the cavities. This is a rare example of a decay mechanism being made to play a constructive role in quantum information processing. The scheme is comparatively easy to implement, requiring the minimal technology of being able to trap a single three level atom in a cavity.

Storage and distribution of quantum information are key elements of quantum information processing and quantum communication. Here, using atom-photon entanglement as the main physical resource, we experimentally demonstrate the preparation of a distant atomic quantum memory. Applying a quantum teleportation protocol on a locally prepared state of a photonic qubit, we realized this so-called rem...

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...

Abstract: In this contribution, we study a single Cooper pair box interacts with a single cavity mode. We show the roles played by the detuning parameters and charged capacities on the degree of entanglement. For large values of the detuning parameter the survival entanglement increases on the expanse of the degree of entanglement. We generate a maximum entangled state and use it to perform the...

Teleportation may be taken as sending and extracting quantum information through quantum channels. In this report, it is shown that to get the maximal probability of exact teleportation through partially entangled quantum channels, the sender (Alice) need only to operate a measurement which satisfy an “entanglement matching” to this channel. An optimal strategy is also provided for the receiver...

Muonium (M = μe) bound state effects are shown to decrease the muon decay rate by a factor of 1 − 5αme/mμ = 0.9999987. That small 1.3 ppm shift is near the sensitivity of proposed muon lifetime measurements. The annihilation rate Γ(M → νeν̄μ) is also computed and found to be ≃ 6.6 × 10Γ(μ → eνeν̄μ). Other potential medium effects on stopped muon decay are briefly discussed. The muon lifetime, τμ,...
