PCTS Series - Nonequilibrium Physics Strongly Interacting Matter & Light

"Parametric Amplification of Quantum Signals"*

Location: Jadwin Hall, PCTS Room 407

Time: 11:00 AM

Speaker(s): Michel Devoret, Yale University

*Description:* Quantum Mechanics puts a limit on how small the 
degradation of information passing through an amplifier can be. It is 
known theoretically that the minimum noise added by an amplifier to the 
signal amounts, in phase preserving mode, to at least half a photon at 
the signal frequency. Is it possible to construct an amplifier working 
at microwave frequencies that would reach this quantum limit and still 
be practical in terms of gain, bandwidth and dynamical range? We will 
present recent work by our group aiming at answering this question, 
which is of crucial importance for the readout of solid state qubits, 
and more generally, for measurement of very weak electromagnetic signals 
in various areas of science.
