How "Quantum" is your Quantum Computer? Macrorealism-based Benchmarking via Mid-Circuit Parity Measurements
Ben Zindorf, Lorenzo Braccini, Debarshi Das +1
To perform meaningful computations, Quantum Computers (QCs) must scale to macroscopic levels - i.e., to a large number of qubits - an objective pursued by most quantum companies. H…
Nonclassicality of a Macroscopic Qubit-Ensemble via Parity Measurement Induced Disturbance
Lorenzo Braccini, Debarshi Das, Ben Zindorf +3
We propose an experimental scheme to test the nonclassicality of a macroscopic ensemble of qubits, through the violation of the classical notion of macrorealism (MR) via the fundam…
Superpositions of Quantum Gaussian Processes
Lorenzo Braccini, Sougato Bose, Alessio Serafini
We generalise the Gaussian formalism of Continuous Variable (CV) systems to describe their entanglement with Discrete Variable (DV) systems, leading to superpositions of CV Gaussia…
Logarithmic lightcones in the multiparticle Anderson model with sparse interactions
Daniele Toniolo, Sougato Bose
We prove that the dynamics of the one-dimensional model with random magnetic field perturbed by a sparse set of terms with a large coupling constant gives rise t…
A Spin-Based Pathway to Testing the Quantum Nature of Gravity
Sougato Bose, Anupam Mazumdar, Roger Penrose +52
A key open problem in physics is the correct way to combine gravity (described by general relativity) with everything else (described by quantum mechanics). This problem suggests t…
Destructive Interference of Inertial Noise in Matter-wave Interferometry
Meng-Zhi Wu, Marko Toroš, Sougato Bose +1
Matter-wave interferometry is highly susceptible to inertial acceleration noises arising from the vibration of the experimental apparatus. There are various methods for noise suppr…
