Maximizing Nonclassicality of Massive Objects via Quantum Zeno Effect
Debarshi Das, Pritam Roy, Marko Toroš +3
For testing quantum mechanics in the macroscopic domain, a major challenge is to devise effective means for enhancing the observable nonclassical signatures despite the ubiquitous…
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. H…
The path towards measuring the gravitational field of proton bunches at accelerators
Daniel Braun, Rongrong Cai, Pascal Hermes +6
The Newtonian law describing the gravitational interaction of non-relativistic (slowly moving) gravitating matter, has been tested in many laboratory experiments with very high pre…
Long-Baseline Atom Interferometry
Antun Balaz, Diego Blas, Oliver Buchmueller +50
Long-baseline atom interferometry is a promising technique for probing various aspects of fundamental physics, astrophysics and cosmology, including searches for ultralight dark ma…
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…
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…
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…
MAQRO -- BPS 2023 Research Campaign Whitepaper
Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer +43
The objective of the proposed MAQRO mission is to harness space for achieving long free-fall times, extreme vacuum, nano-gravity, and cryogenic temperatures to test the foundations…
Quantum Technologies in Space
Rainer Kaltenbaek, Antonio Acin, Laszlo Bacsardi +17
Recently, the European Commission supported by many European countries has announced large investments towards the commercialization of quantum technology (QT) to address and mitig…
Gravitational Decoherence
Angelo Bassi, André Großardt, Hendrik Ulbricht
We discuss effects of loss of coherence in low energy quantum systems caused by or related to gravitation, referred to as gravitational decoherence. These effects, resulting from r…
Effects of Newtonian gravitational self-interaction in harmonically trapped quantum systems
André Großardt, James Bateman, Hendrik Ulbricht +1
The Schrödinger-Newton equation has gained attention in the recent past as a nonlinear modification of the Schrödinger equation due to a gravitational self-interaction. Such a modi…
