An integrated source of broadband quadrature squeezed light
Ulrich B. Hoff, Bo M. Nielsen, Ulrik L. Andersen
An integrated silicon nitride resonator is proposed as an ultra-compact source of bright single-mode quadrature squeezed light at 850 nm. Optical properties of the device are inves…
Ab-initio Quantum Enhanced Optical Phase Estimation Using Real-time Feedback Control
Adriano A. Berni, Tobias Gehring, Bo M. Nielsen +3
Optical phase estimation is a vital measurement primitive that is used to perform accurate measurements of various physical quantities like length, velocity and displacements. The…
Quantum-enhanced micro-mechanical displacement sensitivity
Ulrich B. Hoff, Glen I. Harris, Lars S. Madsen +5
We report on a hitherto unexplored application of squeezed light: for quantum-enhancement of mechanical transduction sensitivity in microcavity optomechanics. Using a toroidal sili…
Breakdown of the classical description of a local system
Eran Kot, Niels Grønbech-Jensen, Bo M. Nielsen +3
We provide a straightforward demonstration of a fundamental difference between classical and quantum mechanics for a single local system; namely the absence of a joint probability…
Optoelectronic cooling of mechanical modes in a semiconductor nanomembrane
K. Usami, A. Naesby, T. Bagci +5
Optical cavity cooling of mechanical resonators has recently become a research frontier. The cooling has been realized with a metal-coated silicon microlever via photo-thermal forc…
Directly estimating non-classicality
A. Mari, K. Kieling, B. Melholt Nielsen +2
We establish a method of directly measuring and estimating non-classicality - operationally defined in terms of the distinguishability of a given state from one with a positive Wig…
