Gravitationally Induced Entanglement of Matter in Quadratic Curvature Gravity and Constraints on Ghost Mass
Linda M. van Manen, Tim Blankenstein, Anupam Mazumdar
We investigate gravitationally generated entanglement in two quantum harmonic oscillators induced by quadratic (Stelle) gravity, including corrections up to post-Newtonian or…
Differential and Common Decoherence Modes in Witnessing the Quantum Gravity-Induced Entanglement of Matter
Ryan Rizaldy, Helen M Sheehy, Tian Zhou +1
In the context of the QGEM (Quantum Gravity-induced Entanglement of Masses) experiment, we consider two adjacent matter-wave interferometers in linear and parallel configurations t…
Entanglement dynamics through electromagnetic interactions in single-electron traps
Pablo Guillermo Carmona Rufo, Anupam Mazumdar, Carlos Sabín
We study the dynamics of quantum entanglement between two harmonically trapped electrons interacting via the electromagnetic force. Starting from two-mode Gaussian states at therma…
Graviton-mediated entanglement due to light bending from a quantum rotor
Dripto Biswas, Sougato Bose, Anupam Mazumdar +1
One of the key tests of the quantum nature of gravity is to test whether the virtual mediator of gravity between matter and photon gives rise to the quantum light-bending phenomeno…
Witnessing entanglement between photon and matter due to graviton exchange
Arijit Dutta, Marko Toroš, Sougato Bose +1
The paper presents a scheme to detect entanglement arising from the quantum nature of gravity between a spin qubit and photons, using Stokes parameters. One of the crucial tests of…
Two-dimensional matter-wave interferometer, rotational dynamics, and spin contrast
Ryan Rizaldy, Shrestha Mishra, Anupam Mazumdar
We investigate a two-dimensional matter-wave interferometer where both spatial and rotational dynamics of a nanoparticle are intertwined in closing the one-loop interferometer in t…
Spatial superposition for a two-dimensional matter-wave interferometer in an inverted harmonic potential with gyroscopic rotational stability
Ryan Rizaldy, Tian Zhou, Run Zhou +1
This study presents a mathematical model of the spatial and rotational motion of a nanodiamond in an inverted harmonic potential to create a macroscopic quantum spatial superpositi…
Momentum Diffusion, Decoherence and Drag Force on a Magnetic Nanoparticle
Agya Sewara Alam, Anupam Mazumdar
In this paper, we will provide a complete derivation of the decoherence rate for a magnetic nanoparticle in quantum superposition in the presence of the fluctuating electromagnetic…
Random acceleration noise on Stern-Gerlach Interferometry in a Harmonic Trap
Sneha Narasimha Moorthy, Andrew Geraci, Sougato Bose +1
We analyze decoherence in a one-loop Stern--Gerlach--type matter-wave interferometer for a massive nanoparticle embedded with a nitrogen vacancy (NV)-centered nanodiamond evolving…
Magnetic levitation and spatial superposition of a nanodiamond with a current-carrying chip
Qian Xiang, Shafaq Gulzar Elahi, Andrew Geraci +2
We propose a current-carrying-chip scheme for generating spatial quantum superpositions using a levitating nanodiamond with a built-in nitrogen-vacancy (NV) centre defect. Our setu…
