Non-degenerate, three-wave mixing with the Josephson ring modulator
Baleegh Abdo, Archana Kamal, Michel H. Devoret
The Josephson ring modulator (JRM) is a device, based on Josephson tunnel junctions, capable of performing non-degenerate mixing in the microwave regime without losses. The generic…
Gain, directionality and noise in microwave SQUID amplifiers: Input-output approach
Archana Kamal, John Clarke, Michel Devoret
We present a new theoretical framework to analyze microwave amplifiers based on the dc SQUID. Our analysis applies input-output theory generalized for Josephson junction devices bi…
Implementation of low-loss superinductances for quantum circuits
Nicholas A. Masluk, Ioan M. Pop, Archana Kamal +2
The simultaneous suppression of charge fluctuations and offsets is crucial for preserving quantum coherence in devices exploiting large quantum fluctuations of the superconducting…
Evidence for coherent quantum phase-slips across a Josephson junction array
Vladimir E. Manucharyan, Nicholas A. Masluk, Archana Kamal +3
Superconducting order in a sufficiently narrow and infinitely long wire is destroyed at zero temperature by quantum fluctuations, which induce slips of the phase of the order…
