Optimal Superpositions for Particle Detection via Quantum Phase
Eva Kilian, Marko Toroš, P. F. Barker +1
Exploiting quantum mechanics for sensing offers unprecedented possibilities. State of the art proposals for novel quantum sensors often rely on the creation of large superpositions…
Measurement of single nanoparticle anisotropy by laser induced optical alignment and Rayleigh scattering for determining particle morphology
Markus Rademacher, Jonathan Gosling, Antonio Pontin +4
We demonstrate the measurement of nanoparticle shape by angularly resolved Rayleigh scattering of single optical levitated particles that are oriented in space via the trapping lig…
Controlling mode orientations and frequencies in levitated cavity optomechanics
A. Pontin, H. Fu, J. H. Iacoponi +2
Cavity optomechanics offers quantum cooling, quantum control and measurement of small mechanical oscillators. However the optical backactions that underpin quantum control can sign…
Measurement of the motional heating of a levitated nanoparticle by thermal light
A. T. M. Anishur Rahman, P. F. Barker
We report on measurements of photon induced heating of silica nanospheres levitated in vacuum by a thermal light source formed by a superluminescent diode. Heating of the nanospher…
Imaging based feedback cooling of a levitated nanoparticle
Yosuke Minowa, Keisuke Kato, Shoki Ueno +4
Imaging-based detection of the motion of the levitated nanoparticles complements a widely-used interferometric detection method, providing a precise and robust way to estimate the…
Entanglement based tomography to probe new macroscopic forces
Peter F. Barker, Sougato Bose, Ryan J. Marshman +1
Quantum entanglement provides a novel way to test short distance physics in the non-relativistic regime. We will provide a protocol to {\it potentially} test new physics by bringin…
