Physical implementation of topologically decoherence-protected superconducting qubits
Zheng-Yuan Xue, Z. D. Wang, Shi-Liang Zhu
We propose a scenario to physically implement a kind of topologically decoherence-protected qubit using superconducting devices coupled to a micro-wave cavity mode with unconventio…
Simple unconventional geometric scenario of one-way quantum computation with superconducting qubits inside a cavity
Zheng-Yuan Xue, Z. D. Wang
We propose a simple unconventional geometric scenario to achieve a kind of nontrivial multi-qubit operations with superconducting charge qubits placed in a microwave cavity. The pr…
Quantum Critical Dynamics of A Qubit Coupled to An Isotropic Lipkin-Meshkov-Glick Bath
H. T. Quan, Z. D. Wang, C. P. Sun
We explore a dynamic signature of quantum phase transition (QPT) in an isotropic Lipkin-Meshkov-Glick (LMG) model by studying the time evolution of a central qubit coupled to it. W…
Conditional Entanglement
Dong Yang, Michal Horodecki, Z. D. Wang
Based on the ideas of {\it quantum extension} and {\it quantum conditioning}, we propose a generic approach to construct a new kind of entanglement measures called {\it conditional…
