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…
Hybrid quantum circuits: Superconducting circuits interacting with other quantum systems
Ze-Liang Xiang, Sahel Ashhab, J. Q. You +1
Hybrid quantum circuits combine two or more physical systems, with the goal of harnessing the advantages and strengths of the different systems in order to better explore new pheno…
Speed limits for quantum gates in multi-qubit systems
S. Ashhab, P. C. de Groot, Franco Nori
We use analytical and numerical calculations to obtain speed limits for various unitary quantum operations in multiqubit systems under typical experimental conditions. The operatio…
Implementing general measurements on linear optical and solid-state qubits
Yukihiro Ota, Sahel Ashhab, Franco Nori
We show a systematic construction for implementing general measurements on a single qubit, including both strong (or projection) and weak measurements. We mainly focus on linear op…
Entanglement amplification via local weak measurements
Yukihiro Ota, Sahel Ashhab, Franco Nori
We propose a measurement-based method to produce a maximally-entangled state from a partially-entangled pure state. Our goal can be thought of as entanglement distillation from a s…
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…
