Spin-Dependent Force and Inverted Harmonic Potential for Rapid Creation of Macroscopic Quantum Superpositions
Run Zhou, Qian Xiang, Anupam Mazumdar
Creating macroscopic spatial superposition states is crucial for investigating matter-wave interferometry and advancing quantum sensor technology. Currently, two potential methods…
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…
Dephasing due to electromagnetic interactions in spatial qubits
Martine Schut, Herre Bosma, MengZhi Wu +3
Matter-wave interferometers with micro-particles will enable the next generation of quantum sensors to probe minute quantum phase information. Therefore, estimating the loss of coh…
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…
