Proposal for creating spatial superposition of a large mass in a RF trap
Martine Schut, Jackson Tiong, Valerio Scarani
Engineering coherent spatial superpositions of levitated large masses is an ongoing challenge. Borrowing from recent experimental work, we consider a charged mass of hundreds of na…
Probing metric fluctuations with the spin of a particle in a quantum simulation
Jiannis K. Pachos, Patricio Salgado-Rebolledo, Martine Schut
Exploring potential empirical manifestations of quantum gravity is a challenging pursuit. In this study, we utilise a lattice representation of a (2+1)D massive gravity toy model i…
Diamagnetic microchip traps for levitated nanoparticle entanglement experiments
Shafaq Gulzar Elahi, Martine Schut, Andrew Dana +4
The Quantum Gravity Mediated Entanglement (QGEM) protocol offers a novel method to probe the quantumness of gravitational interactions at non-relativistic scales. This protocol lev…
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…
Magnetic field fluctuations induced decoherence of a diamagnetic nanosphere
Ruiyun Zhang, Martine Schut, Anupam Mazumdar
This paper provides a simple derivation of the decoherence rate for a diamagnetic nanoparticle in the presence of fluctuations of the magnetic field in a thermal environment. Diama…
Spin contrast, finite temperature, and noise in matter-wave interferometer
Tian Zhou, Ryan Rizaldy, Martine Schut +1
In this paper, we will show how finite-temperature corrections and spin-dependent/independent noise will affect the contrast in a matter-wave interferometer, especially with massiv…
