Short-time decoherence of Josephson charge qubit nonlinearly coupling with its environment
Xian-Ting Liang, Yong-Jian Xiong
At first, we generally investigate the short-time decoherence of a qubit nonlinearly coupling with a bath. The measure of the decoherence is chosen as the maximum norm of the devia…
The Loss of fidelity due to quantum leakage for Josephson charge qubits
Xian-Ting Liang, Yong-Jian Xiong
In this paper we calculate the loss of fidelity due to quantum leakage for the Josephson charge qubit (JCQ) in virtue of the Mathieu functions. It is shown that for an present typi…
Entanglement-assisted classical information capacity of the amplitude damping channel
Xian-Ting Liang
In this paper, we calculate the entanglement-assisted classical information capacity of amplitude damping channel and compare it with the particular mutual information which is con…
Short-time decoherence of Josephson charge qubits
Xian-Ting Liang
In this paper we investigate the short-time decoherence of single Josephson charge qubit (JCQ). The measure of decoherence is chosen as the maximum norm of the deviation density op…
