Rotational stability in nanorotor and spin contrast in one-loop interferometry in the Stern-Gerlach setup
Ryan Rizaldy, Tian Zhou, Sougato Bose +1
The rotation of a nanoparticle in a quantum system has many applications, from theory to experiments. This paper will treat nanoparticle rotational dynamics for spin-embedded nanor…
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…
Decoherence rate expression due to air molecule scattering in spatial qubits
Martine Schut, Patrick Andriolo, Marko Toroš +2
We provide a solution for decoherence in spatial superpositions due to scattering/collision with air molecules. This result reproduces the short- and long-wavelength limits known i…
Exponential Expansion of Massive Schrödinger Cats for Sensing and Entanglement
Lorenzo Braccini, Alessio Serafini, Sougato Bose
Schrödinger cat states of levitated masses have several applications in sensing and, offer an avenue to explore the fundamental nature -- classical vs nonclassical -- of gravity, e…
Gyroscopic stability for nanoparticles in Stern-Gerlach Interferometry and spin contrast
Tian Zhou, Sougato Bose, Anupam Mazumdar
Creating macroscopic spatial quantum superposition with a nanoparticle has a multitude of applications, ranging from testing the foundations of quantum mechanics, matter-wave inter…
Relativistic Effects on Entangled Single-Electron Traps
Marko Toroš, Patrick Andriolo, Martine Schut +2
The manipulation of individual charged particles has been deeply explored in physics's theoretical and experimental domains during the past decades. It is the pillar of several exi…
Relativistic Dips in Entangling Power of Gravity
Marko Toroš, Martine Schut, Patrick Andriolo +2
The salient feature of both classical and quantum gravity is its universal and attractive character. However, less is known about the behaviour and build-up of quantum correlations…
Inertial Torsion Noise in Matter-Wave Interferometers for Gravity Experiments
Meng-Zhi Wu, Marko Toroš, Sougato Bose +1
Matter-wave interferometry is susceptible to non-inertial noise sources, which can induce dephasing and a resulting loss of interferometric visibility. Here, we focus on inertial t…
Phonon-induced contrast in a matter-wave interferometer
Qian Xiang, Run Zhou, Sougato Bose +1
Utilizing the Stern-Gerlach apparatus to create matter-wave superposition states is a long-sought-after goal, not only due to its potential applications in the quantum realm but al…
Dark Matter Searches with Levitated Sensors
Eva Kilian, Markus Rademacher, Jonathan M. H. Gosling +8
Motivated by the current interest in employing quantum sensors on Earth and in space to conduct searches for new physics, we provide a perspective on the suitability of large-mass…
Entanglement Entropy in Scalar Quantum Electrodynamics
Samuel Fedida, Anupam Mazumdar, Sougato Bose +1
We find the entanglement entropy of a subregion of the vacuum state in scalar quantum electrodynamics, working perturbatively to the 2-loops level. Doing so leads us to derive the…
Digital quantum simulation of gravitational optomechanics with IBM quantum computers
Pablo Guillermo Carmona Rufo, Anupam Mazumdar, Sougato Bose +1
We showcase the digital quantum simulation of the action of a Hamiltonian that governs the interaction between a quantum mechanical oscillator and an optical field, generating quan…
