Multi-Path Interferometric Josephson Directional Amplifier for Qubit Readout
Baleegh Abdo, Nick Bronn, Oblesh Jinka +3
We realize and characterize a quantum-limited, directional Josephson amplifier suitable for qubit readout. The device consists of two nondegenerate, three-wave-mixing amplifiers th…
Characterization of hidden modes in networks of superconducting qubits
Sarah Sheldon, Martin Sandberg, Hanhee Paik +4
We present a method for detecting electromagnetic (EM) modes that couple to a superconducting qubit in a circuit-QED architecture. Based on measurement-induced dephasing, this tech…
Gyrator operation using Josephson mixers
Baleegh Abdo, Markus Brink, Jerry M. Chow
Nonreciprocal microwave devices, such as circulators, are useful in routing quantum signals in quantum networks and protecting quantum systems against noise coming from the detecti…
