Heisenberg constraints on mesoscopic and molecular amplifiers
U. Gavish, B. Yurke, Y. Imry
Heisenberg uncertainty relations for current components impose constraints on the performance of linear amplifiers. Here we derive such constraints for amplifiers in which the inpu…
Generalized constraints on quantum amplification
U. Gavish, B. Yurke, Y. Imry
We derive quantum constraints on the minimal amount of noise added in linear amplification involving input or output signals whose component operators do not necessarily have c-num…
Applications of nonequilibrium Kubo formula to the detection of quantum noise
U. Gavish, Y. Imry, B. Yurke
The Kubo fluctuation-dissipation theorem relates the current fluctuations of a system in an equilibrium state with the linear AC-conductance. This theorem holds also out of equilib…
What quantity is measured in an excess noise experiment?
U. Gavish, Y. Imry, Y. Levinson +1
Consider a measurement in which the current coming out of a mesoscopic sample is filtered around a given frequency, amplified, measured and squared. Then this process is repeated m…
