Efficient computation of average subsystem Bures distance between fermionic Gaussian states
Zhouhao Guo, M. A. Rajabpour, Jiaju Zhang
The average subsystem trace distance has been proposed as an indicator of quantum many-body chaos and integrability. However, evaluating it presents two main difficulties: high com…
Necessity of entanglement for the typicality argument in statistical mechanics
Pedro S. Correia, Gabriel Dias Carvalho, Thiago R. de Oliveira
Typicality arguments replace the postulated mixed state ensembles of statistical mechanics with pure states sampled uniformly at random, explaining why most microstates of large sy…
Equilibration and the eigenstate thermalization hypothesis as limits to observing macroscopic quantum superpositions
Gabriel Dias Carvalho, Pedro S. Correia, Thiago R. de Oliveira
Macroscopic quantum superpositions are widely believed to be unobservable because large systems cannot be perfectly isolated from their environments. Here, we show that even under…
Interaction-free measurement of multiple objects using a universal integrated photonic processor
Sara Franco, Anita Camillini, Ernesto F. Galvão
The phenomenon of interaction-free measurement (IFM) enables the probabilistic detection of an absorbing object with reduced photon absorption. We report the experimental implement…
Two-particle scattering on general graphs
Luna Lima Keller, Daniel Jost Brod
Quantum walks in general graphs, or more specifically scattering on graphs, encompass enough complexity to perform universal quantum computation. Any given quantum circuit can be b…
Exact analysis of AC sensors based on Floquet time crystals
Andrei Tsypilnikov, Matheus Fibger, Fernando Iemini
We discuss the behavior of general Floquet time crystals (FTCs), including prethermal ones, in closed systems acting as AC sensors. We provide an analytical treatment of their quan…
