Phase-shaped driving and buffer regions stabilize a superconducting parametric amplifier array for broadband directional gain with low noise.
Coupled asymmetric SQUIDs enable non-reciprocal traveling wave amplification with wide bandwidth, large dynamic range, and less cryogenic hardware.
A chain of asymmetric SQUIDs enables wideband non-reciprocal gain, removing bulky cryogenic circulators for multiplexed qubit readout.
Strong coupling between a nanostructure resonator and field emission current enables low-noise, low-power RF signal amplification and detection.
Orthogonal resonant modes isolate input, pump, and output signals, cutting filter loss and noise in varactor-based parametric amplification.
