Conditions for the freezing phenomena of geometric measure of quantum discord for arbitrary two-qubit X states under non-dissipative dephasing noises
Wei Song, Zhuo-Liang Cao
We study the dynamics of geometric measure of quantum discord (GMQD) under the influences of two local phase damping noises. Consider the two qubits initially in arbitrary X-states…
Geometric measure of quantum discord and the geometry of a class of two-qubit states
Wei Song, Long-Bao Yu, Ping Dong +3
We investigate the geometric picture of the level surfaces of quantum entanglement and geometric measure of quantum discord (GMQD) of a class of X-states, respectively. This pictor…
Quantum computation with quantum-dot spin qubits inside a cavity
Ping Dong, Ming Yang, Zhuo-Liang Cao
Universal set of quantum gates are realized from the conduction-band electron spin qubits of quantum dots embedded in a microcavity via two-channel Raman interaction. All of the ga…
General quantum phase estimation and calibration of a timepiece in a quantum dot system
Ping Dong, Zhuo-Liang Cao
We present a physical scheme for implementing quantum phase estimation via weakly coupled double quantum-dot molecules embedded in a microcavity. During the same process of impleme…
Discrete quantum Fourier transform in coupled semiconductor double quantum dot molecules
Ping Dong, Ming Yang, Zhuo-Liang Cao
In this Letter, we present a physical scheme for implementing the discrete quantum Fourier transform in a coupled semiconductor double quantum dot system. The main controlled-R gat…
Implementation of Grover search algorithm with Josephson charge qubits
Xiao-Hu Zheng, Ping Dong, Zheng-Yuan Xue +1
A scheme of implementing the Grover search algorithm based on Josephson charge qubits has been proposed, which would be a key step to scale more complex quantum algorithms and very…
