A Spin-Based Pathway to Testing the Quantum Nature of Gravity
Sougato Bose, Anupam Mazumdar, Roger Penrose +52
A key open problem in physics is the correct way to combine gravity (described by general relativity) with everything else (described by quantum mechanics). This problem suggests t…
Enhancement of the effects due to the Schrödinger-Newton equation
Davide Giordano Ario Altamura, José Luis Gaona-Reyes, Elliot Simcox +2
The Schrödinger-Newton (SN) equation introduces a nonlinear self-gravitational term to the standard Schrödinger equation, offering a paradigmatic model for semiclassical gravity.…
Measuring Decoherence Due to Quantum Vacuum Fluctuations
Anirudh Gundhi, Hendrik Ulbricht
The interaction of a particle with vacuum fluctuations--which theoretically exist even in the complete absence of matter--can lead to observable irreversible decoherence if it were…
Generation of classical non-Gaussian distributions by squeezing a thermal state into non-linear motion of levitated optomechanics
Rafael Muffato, Tiberius Georgescu, Jack Homans +6
We report on an experiment achieving the dynamical generation of non-Gaussian states of motion of a levitated optomechanical system. We access intrinsic Duffing-like nonlinearities…
Massive quantum systems as interfaces of quantum mechanics and gravity
Sougato Bose, Ivette Fuentes, Andrew A. Geraci +7
The traditional view from particle physics is that quantum gravity effects should only become detectable at extremely high energies and small length scales. Due to the significant…
Squeezing below the ground state of motion of a continuously monitored levitating nanoparticle
Qiongyuan Wu, Diana A. Chisholm, Rafael Muffato +5
Squeezing is a crucial resource for quantum information processing and quantum sensing. In levitated nanomechanics, squeezed states of motion can be generated via temporal control…
