Journal ArticleDOI
Observation of parametric amplification and deamplification in a Josephson parametric amplifier
Bernard Yurke,LR Corruccini,P.G. Kaminsky,L. W. Rupp,A. D. Smith,A. H. Silver,R. W. Simon,Edward A. Whittaker +7 more
TL;DR: In this paper, the authors present the results of an experimental effort to generate squeezed microwave radiation using the phase-sensitive gain of a Josephson parametric amplifier, which is used for both doubly degenerate and four-photon mode.
Journal ArticleDOI
Observation of 4.2-K equilibrium-noise squeezing via a Josephson-parametric amplifier.
Bernard Yurke,P. G. Kaminsky,R. E. Miller,Edward A. Whittaker,A. D. Smith,A. H. Silver,R. W. Simon +6 more
TL;DR: In this paper, the authors demonstrated 42% squeezing of 4.2-K thermal noise using a Josephson-parametric amplifier operated at 19.4 GHz with an excess noise of 0.28 K referred to the input port.
Journal ArticleDOI
Observation of zero-point noise squeezing via a Josephson-parametric amplifier.
R. Movshovich,Bernard Yurke,P.G. Kaminsky,A. D. Smith,A. H. Silver,R. W. Simon,M.V. Schneider +6 more
TL;DR: In this article, a Josephson-parametric amplifier with a double-sideband noise temperature of 0.446 K was used to squeeze out vacuum-fluctuation noise at 19.16 GHz.
Journal ArticleDOI
Observation of 4.2 equilibrium noise squeezing via a Josephson-parametric amplifier
Bernard Yurke,P.G. Kaminsky,R. E. Miller,Edward A. Whittaker,A. D. Smith,A. H. Silver,R. W. Simon +6 more
TL;DR: The authors observed the squeezing of 4.2 K thermal noise using a Josephson parametric amplifier operated in the degenerate mode at 19.4 GHz with a 42% reduction in the equilibrium noise.
Journal ArticleDOI
Chaos and bifurcation in Josephson voltage-controlled oscillators
TL;DR: In this paper, the performance of a Josephson voltage-controlled oscillator consisting of a tunnel junction shunted by a small inductor in series with a small bias resistor (a resistive SQUID circuit) was reported.
