Quantum noise and its evasion in feedback oscillators
Hudson A. Loughlin, Vivishek Sudhir
We study an abstract model of an oscillator realized by an amplifier embedded in a positive feedback loop. The power and frequency stability of the output of such an oscillator are…
Causal State Estimation and the Heisenberg Uncertainty Principle
Junxin Chen, Benjamin B. Lane, Su Direkci +5
The observables of a noisy quantum system can be estimated by appropriately filtering the records of their continuous measurement. Such filtering is relevant for state estimation a…
Unification of thermal and quantum noise in gravitational-wave detectors
Chris Whittle, Lee McCuller, Vivishek Sudhir +1
Contemporary gravitational-wave detectors are fundamentally limited by thermal noise -- due to dissipation in the mechanical elements of the test mass -- and quantum noise -- from…
