Simultaneous cooling of an artificial atom and its neighboring quantum system
J. Q. You, Yu-xi Liu, Franco Nori
We propose an approach for cooling both an artificial atom (e.g., a flux qubit) and its neighboring quantum system, the latter modeled by either a quantum two-level system or a qua…
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…
Switchable coupling between charge and flux qubits
Xiao-Ling He, J. Q. You, Yu-xi Liu +2
We propose a hybrid quantum circuit with both charge and flux qubits connected to a large Josephson junction that gives rise to an effective inter-qubit coupling controlled by the…
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.…
