Evidencing Macroscopic Quantum Coherence using Confined Uniform Magnetic Field
Dipankar Home, Harsh Talwar, Nilaj Saha +2
A previously unexplored scheme is devised for creating and certifying coherent quantum superposition of distinctly separated states of a spin-tagged massive object passing through…
Technical Proposal for the Atom Interferometer CERN Experiment (AICE) Facility
Gianluigi Arduini, Nadja Augst, Mark G. Bason +79
We present the technical proposal for the Atom Interferometer CERN Experiment (AICE), a m vertical atom interferometer to be installed against the wall of the PX…
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…
How to Test Bell Nonlocality for Gravity?
Debarshi Das, Mir Alimuddin, Simon Storz +2
We propose an experiment to test Bell nonlocality, a genuine nonclassicality, for the gravitational field. Two masses with embedded entangled spins (e.g., two diamonds with their N…
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…
Precision gravimetry via harnessing interaction-induced resonances in optical lattices
Hassan Manshouri, Moslem Zarei, Mehdi Abdi +3
By confining a Bose-Einstein condensate in a vertical lattice subjected to a gravitational potential, we analyze the quantum Fisher information to determine its scaling with respec…
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…
Effective Repulsive Action of Gravitational Quantum Superpositions Under Postselection
Sougato Bose, Lev Vaidman
A classic feature of gravity is that it is an attractive force. If a source mass is prepared in a localized (classical- like) state, it will cause another probe mass to move toward…
Mass-Independent Gravitationally Induced Entanglement
Lorenzo Braccini, Alessio Serafini, Sougato Bose
We analytically solve the entangling quantum dynamics of two interacting Stern-Gerlach Interferometers~(SGI). Each SGI exploits an operator-valued force applied by a qubit to creat…
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…
