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…
Violating Bell's inequality with an artificial atom and a cat state in a cavity
Brian Vlastakis, Andrei Petrenko, Nissim Ofek +11
The `Schrödinger's cat' thought experiment highlights the counterintuitive facet of quantum theory that entanglement can exist between microscopic and macroscopic systems, producin…
Full coherent frequency conversion between two microwave propagating modes
Baleegh Abdo, Katrina Sliwa, Flavius Schackert +5
We demonstrate full frequency conversion in the microwave domain using a Josephson three-wave mixing device pumped at the difference between the frequencies of its fundamental eige…
