Entanglement dynamics through electromagnetic interactions in single-electron traps
Pablo Guillermo Carmona Rufo, Anupam Mazumdar, Carlos SabÃn
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…
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…
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…
