Entangled Coherent State Qubits in an Ion Trap
We show how entangled qubits can be encoded as entangled coherent states of two–dimensional centre-of-mass vibrational motion for two ions in an ion trap. The entangled qubit state is equivalent to the canonical Bell state, and we introduce a proposal for entanglement transfer from the two vibrational modes to the electronic states of the two ions in order for the Bell state to be detected by r...

متن کاملEntangled State Reconstruction of an Electron in the Penning Trap
Entanglement [1] is one of the essential and most puzzling features of quantum mechanics. It is also the basic ingredient and resource of quantum informa tion processing: quantum teleportation [2, 3], quan tum dense coding [4], quantum cryptography [5], and quantum computation [6] are just a few examples of the possibilities offered by sharing quantum en tanglement. Recently, for example, it...
متن کاملDephasing of entangled qubits
We investigate the influence of nearby two-level systems on the dynamics of a qubit. The intrinsic decoherence is given by a coupling of both the qubit and the two-level systems to a heat bath. Assuming weak interactions between the qubit and the two-level systems we show that the dephasing of the qubit follows a multi-exponential decay. For a flat distribution of energy splittings of the two-l...
متن کاملTeleportation via an Entangled Coherent Channel and Decoherence Effect on This Channel
We study an entangled two-mode coherent state within the framework of2×2-dimensional Hilbert space. We investigate the problem of quantum teleportation ofa superposition coherent state via an entangled coherent channel. By three differentmeasures with the titles ``minimum assured fidelity (MASF)”, ``average teleportationfidelity” and ``optimal fidelity (f)” we study the ...
