A hybrid quantum circuit consisting of a superconducting flux qubit coupled to both a spin ensemble and a transmission-line resonator
Ze-Liang Xiang, Xin-You Lu, Tie-Fu Li +2
We propose an experimentally realizable hybrid quantum circuit for achieving a strong coupling between a spin ensemble and a transmission-line resonator via a superconducting flux…
Quantum-criticality-induced strong Kerr nonlinearities in optomechanical systems
Xin-You Lü, Wei-Min Zhang, Sahel Ashhab +2
We investigate a hybrid electro-optomechanical system that allows us to obtain controllable strong Kerr nonlinearities in the weak-coupling regime. We show that when the controllab…
Confidence and Backaction in the Quantum Filter Equation
Wei Cui, Neill Lambert, Yukihiro Ota +4
We study the confidence and backaction of state reconstruction based on a continuous weak measurement and the quantum filter equation. As a physical example we use the traditional…
Two-qubit gate operations in superconducting circuits with strong coupling and weak anharmonicity
Xin-You Lü, S. Ashhab, Wei Cui +2
We investigate theoretically the implementation of two-qubit gates in a system of two coupled superconducting qubits. In particular, we analyze two-qubit gate operations under the…
