Optimizing Josephson-Ring-Modulator-based Josephson Parametric Amplifiers via full Hamiltonian control
Chenxu Liu, Tzu-Chiao Chien, Michael Hatridge +1
Josephson Parametric Amplifiers (JPA) are nonlinear devices that are used for quantum sensing and qubit readout in the microwave regime. While JPAs regularly operate in the quantum…
Quantum back-action of variable-strength measurement
M. Hatridge, S. Shankar, M. Mirrahimi +9
Measuring a quantum system can randomly perturb its state. The strength and nature of this back-action depends on the quantity which is measured. In a partial measurement performed…
Multiparametric Amplification and Qubit Measurement with a Kerr-free Josephson Ring Modulator
T. -C. Chien, O. Lanes, C. Liu +6
Josephson-junction based parametric amplifiers have become a ubiquitous component in superconducting quantum machines. Although parametric amplifiers regularly achieve near-quantum…
