Nonadiabatic geometric quantum gates that are insensitive to qubit-frequency drifts
Jian Zhou, Sai Li, Guo-Zhu Pan +3
Quantum manipulation based on geometric phases provides a promising way towards robust quantum gates. However, in the current implementation of nonadiabatic geometric phases, opera…
Computable steering criterion for bipartite quantum systems
Guo-Zhu Pan, Jun-Long Zhao, Zhi Lin +3
Quantum steering describes the ability of one observer to nonlocally affect the other observer's state through local measurements, which represents a new form of quantum nonlocal c…
Nonlinear steering criteria for arbitrary two-qubit quantum systems
Guo-Zhu Pan, Ming Yang, Hao Yuan +2
By employing Pauli measurements, we present some nonlinear steering criteria applicable for arbitrary two-qubit quantum systems and optimized ones for symmetric quantum states. The…
Tunable interaction of superconducting flux qubits in circuit QED
Zheng-Yuan Xue, Ya-Fei Li, Jian Zhou +2
We propose to implement tunable interaction of superconducting flux qubits with cavity-assisted interaction and strong driving. The qubits have a three-level Lambda configuration,…
Quantum controlled phase gate and cluster states generation via two superconducting quantum interference devices in a cavity
Zheng-Yuan Xue, Gang Zhang, Ping Dong +2
A scheme for implementing 2-qubit quantum controlled phase gate (QCPG) is proposed with two superconducting quantum interference devices (SQUIDs) in a cavity. The gate operations a…
