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…
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…
Improving the Quality Factor of Microwave Compact Resonators by Optimizing their Geometrical Parameters
K. Geerlings, S. Shankar, E. Edwards +3
Applications in quantum information processing and photon detectors are stimulating a race to produce the highest possible quality factor on-chip superconducting microwave resonato…
