Teleportation of qubit states through dissipative channels: Conditions for surpassing the no-cloning limit
Sahin Kaya Ozdemir, Karol Bartkiewicz, Yu-xi Liu +1
We investigate quantum teleportation through dissipative channels and calculate teleportation fidelity as a function of damping rates. It is found that the average fidelity of tele…
Variable-frequency-controlled coupling in charge qubit circuits: Effects of microwave field on qubit-state readout
Xiao-Ling He, Yu-xi Liu, J. Q. You +1
To implement quantum information processing, microwave fields are often used to manipulate superconuducting qubits. We study how the coupling between superconducting charge qubits…
Control of photon propagation via electromagnetically induced transparency in lossless media
Liang He, Yu-xi Liu, S. Yi +2
We study the influence of a lossless material medium on the coherent storage and quantum state transfer of a quantized probe light in an ensemble of -type atoms. The medium is m…
Quantum Entanglement and Teleportation of Quantum-Dot States in Microcavities
A. Miranowicz, S. K. Ozdemir, Yu-xi Liu +3
Generation and control of quantum entanglement are studied in an equivalent-neighbor system of spatially-separated semiconductor quantum dots coupled by a single-mode cavity field.…
Two-Mode Squeezed States and Entangled States of Two Mechanical Resonators
Fei Xue, Yu-xi Liu, C. P. Sun +1
We study a device consisting of a dc-SQUID with two sections of its loop acting as two mechanical resonators. An analog of the parametric down-conversion process in quantum optics…
