Mechanical Quantum Sensing in the Search for Dark Matter
Daniel Carney, Gordan Krnjaic, David C. Moore +32
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matt…
Detecting Acoustic Blackbody Radiation with an Optomechanical Antenna
Robinjeet Singh, Thomas P. Purdy
Nanomechanical systems are generally embedded in a macroscopic environment where the sources of thermal noise are difficult to pinpoint. We engineer a silicon nitride membrane opto…
Quantum-based vacuum metrology at NIST
Julia Scherschligt, James A. Fedchak, Zeeshan Ahmed +10
The measurement science in realizing and disseminating the unit for pressure in the International System of Units (SI), the pascal (Pa), has been the subject of much interest at th…
Observation of a room-temperature oscillator's motion dominated by quantum fluctuations over a broad audio-frequency band
Jonathan Cripe, Nancy Aggarwal, Robert Lanza +7
We report on the broadband measurement of quantum radiation pressure noise (QRPN) in an optomechanical cavity at room temperature over a broad range of frequencies relevant to grav…
Radiation-Pressure-Mediated Control of an Optomechanical Cavity
Jonathan Cripe, Nancy Aggarwal, Robinjeet Singh +7
We describe and demonstrate a method to control a detuned movable-mirror Fabry-Perot cavity using radiation pressure in the presence of a strong optical spring. At frequencies belo…
A Stable Optical Trap from a Single Optical Field Utilizing Birefringence
Robinjeet Singh, Garrett D. Cole, Jonathan Cripe +1
We report a stable double optical spring effect in an optical cavity pumped with a single optical field that arises as a result of birefringence. One end of the cavity is formed by…
Nearly Optimal Measurement Scheme in a Noisy Mach-Zehnder Interferometer with Coherent and Squeezed Vacuum
Bryan T. Gard, Chenglong You, Devendra K. Mishra +4
The use of an interferometer to perform an ultra-precise parameter estimation under noisy conditions is a challenging task. Here we discuss nearly optimal measurement schemes for a…
Improving photon detector efficiency using a high-fidelity optical CNOT gate
Katherine L Brown, Robinjeet Singh, Joshua H. Mendez Plaskus +2
A significant problem for optical quantum computing is inefficient, or inaccurate photo-detectors. It is possible to use CNOT gates to improve a detector by making a large cat stat…
Quantum Enhanced Magnetometer with Low-Frequency Squeezing
Travis Horrom, Robinjeet Singh, Jonathan P. Dowling +1
We report the demonstration of a magnetometer with noise-floor reduction below the shot-noise level. This magnetometer, based on a nonlinear magneto-optical rotation effect, is enh…
