Three-dimensional squeezing of optically levitated nanospheres
Giacomo Marocco, David C. Moore, Daniel Carney
We propose a protocol to measure impulses beyond the standard quantum limit. The protocol reduces noise in all three spatial dimensions and consists of squeezing a mechanical syste…
On the quantum mechanics of entropic forces
Daniel Carney, Manthos Karydas, Thilo Scharnhorst +2
It was conjectured thirty years ago that gravity could arise from the entropic re-arrangement of information. In this paper, we offer a set of microscopic quantum models which real…
Impulse measurements enhanced with squeezed readout light
Tsai-Chen Lee, Jacob L. Beckey, Giacomo Marocco +1
We quantify how squeezed light can reduce quantum measurement noise to levels below the standard quantum limit in impulse measurements with mechanical detectors. The broadband natu…
Classical-quantum scattering
Daniel Carney, Akira Matsumura
We analyze the framework recently proposed by Oppenheim et al. to model relativistic quantum fields coupled to relativistic, classical, stochastic fields (in particular, as a model…
