Superconducting quantum electronics based on stochastic resonance systems

The principles are developed for amplification of weak informational signals in superconductive quantum interferometers (SQUIDs) based on the effect of stochastic resonance (SR) at arbitrary low temperature and in arrays of SR-SQUIDs. Numerically calculated gain is 30 dB under signal-to-noise ratio...

Description
Summary:The principles are developed for amplification of weak informational signals in superconductive quantum interferometers (SQUIDs) based on the effect of stochastic resonance (SR) at arbitrary low temperature and in arrays of SR-SQUIDs. Numerically calculated gain is 30 dB under signal-to-noise ratio approaching to (10...20) dB. New RF field-controlled SR-antennas for SQUIDs are suggested.
