Journal ArticleDOI
Quantum Theory of Superresolution for Two Incoherent Optical Point Sources
TL;DR: In this paper, it was shown that it is always possible to estimate the separation of two stars, no matter how close they are, regardless of how distant they are from each other.
Journal ArticleDOI
Fundamental quantum limit to waveform estimation.
TL;DR: A quantum Cramer-Rao bound to the error of waveform estimation in quantum sensing is presented and it is shown that the bound can be achieved using quantum estimation and control techniques.
Journal ArticleDOI
Coherent Quantum-Noise Cancellation for Optomechanical Sensors
Mankei Tsang,Carlton M. Caves +1 more
TL;DR: Using a flow chart representation of quantum optomechanical dynamics, coherent quantum-noise-cancellation schemes are designed that can eliminate the backaction noise induced by radiation pressure at all frequencies and thus overcome the standard quantum limit of force sensing.
Journal ArticleDOI
Far-Field Superresolution of Thermal Electromagnetic Sources at the Quantum Limit.
Ranjith Nair,Mankei Tsang +1 more
TL;DR: It is shown via the quantum Cramér-Rao bound that, contrary to the Rayleigh limit in conventional direct imaging, quantum mechanics does not mandate any loss of precision in estimating even deep sub-Rayleigh separations.
Journal ArticleDOI
Cavity quantum electro-optics
TL;DR: In this paper, the quantum dynamics of the coupling between a cavity optical field and a resonator microwave field via the electro-optic effect was studied, and the possibilities of laser cooling of the microwave mode, entanglement between the optical mode and the microwave modes via electrooptic parametric amplification, and back-action-evading optical measurements of a microwave quadrature were pointed out.
