Observing and evading quantum back-action on a kilogram-scale oscillator
Begüm Kabagöz, Eric Oelker, Dhruva Ganapathy +203
Continuous quantum displacement measurements are fundamentally limited by a trade-off between readout imprecision and measurement back-action, constrained by the Heisenberg uncerta…
A robust laser cavity platform for NV-diamond singlet infrared absorption magnetometry
Shao Qi Lim, Alexander A. Wood, Brett C. Johnson +9
The negatively charged nitrogen-vacancy center (NV) in diamond is a versatile platform for quantum magnetometry under ambient conditions. Recently, laser threshold magnetometry…
Approaching the motional ground state of a 10 kg object
Chris Whittle, Evan D. Hall, Sheila Dwyer +197
The motion of a mechanical object -- even a human-sized object -- should be governed by the rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult: th…
Quantum correlations between the light and kilogram-mass mirrors of LIGO
Haocun Yu, L. McCuller, M. Tse +196
Measurement of minuscule forces and displacements with ever greater precision encounters a limit imposed by a pillar of quantum mechanics: the Heisenberg uncertainty principle. A l…
Optical dilution and feedback cooling of a gram-scale oscillator to 6.9 mK
Thomas Corbitt, Christopher Wipf, Timothy Bodiya +5
We report on use of a radiation pressure induced restoring force, the optical spring effect, to optically dilute the mechanical damping of a 1 gram suspended mirror, which is then…
An all-optical trap for a gram-scale mirror
T. Corbitt, Y. Chen, H. Mueller-Ebhardt +7
We report on a stable optical trap suitable for a macroscopic mirror, wherein the dynamics of the mirror are fully dominated by radiation pressure. The technique employs two freque…
