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…

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…
