Strong-Drive Limits in Josephson Circuits: From Chaos to an Unbound-Resonance Threshold
Xinyuan You, Aniket Maiti, Yao Lu
Strong microwave drives enable fast measurement and parametric control in superconducting circuits but can induce transitions out of the intended low-energy manifold. We develop a…
Systematic Construction of Time-Dependent Hamiltonians for Microwave-Driven Josephson Circuits
Yao Lu, Tianpu Zhao, André Vallières +13
Time-dependent electromagnetic drives are fundamental for controlling complex quantum systems, including superconducting Josephson circuits. In these devices, accurate time-depende…
A Linear Quantum Coupler for Clean Bosonic Control
Aniket Maiti, John W. O. Garmon, Yao Lu +3
Quantum computing with superconducting circuits relies on high-fidelity driven nonlinear processes. An ideal quantum nonlinearity would selectively activate desired coherent proces…
Loss tangent fluctuations due to two-level systems in superconducting microwave resonators
André Vallières, Megan E. Russell, Xinyuan You +10
Superconducting microwave resonators are critical to quantum computing and sensing technologies. Additionally, they are common proxies for superconducting qubits when determining t…
