Magnetic noise in macroscopic quantum spatial superposition induced by inverted harmonic oscillator potential
Sneha Narasimha Moorthy, Anupam Mazumdar
We investigate a Stern-Gerlach type matter-wave interferometer where an inhomogeneous magnetic field couples to an embedded spin in a nanoparticle to create spatial superpositions.…
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…
Destructive Interference of Inertial Noise in Matter-wave Interferometry
Meng-Zhi Wu, Marko Toroš, Sougato Bose +1
Matter-wave interferometry is highly susceptible to inertial acceleration noises arising from the vibration of the experimental apparatus. There are various methods for noise suppr…
Evolution of tripartite entanglement in three-qubit Quantum Gravity-Induced Entanglement of Masses (QGEM) with quantum decoherence
Pablo Guillermo Carmona Rufo, Anupam Mazumdar, Carlos Sabín
The recently introduced quantum gravity-induced entanglement of masses (QGEM) protocol aims to test the quantum nature of gravity by witnessing the entanglement produced by the vir…
Entanglement witnesses mediated via axionLike particles
Pablo Guillermo Carmona Rufo, Ayush Kumar, Carlos Sabín +1
Entanglement is solely a quantum property and it can be extremely helpful to test the physics beyond the Standard Model in tabletop experiments with the advent of future quantum te…
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…
Parameter scanning in a quantum-gravity-induced entanglement of masses (QGEM) experiment with electromagnetic screening
Martine Schut, Anupam Mazumdar
Witnessing the quantum nature of spacetime is an exceptionally challenging task. However, the quantum gravity-induced entanglement of matter (QGEM) protocol proposes such a test by…
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…
