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…
Quantum Charging Advantage in Superconducting Solid-State Batteries
Chang-Kang Hu, Chilong Liu, Jingchao Zhao +20
Quantum battery, as a novel energy storage device, offers the potential for unprecedented efficiency and performance beyond the capabilities of classical systems, with broad implic…
Microscopic Quantum Friction
Pedro H. Pereira, F. Impens, C. Farina +2
We report on a microscopic theory of quantum friction. Our approach investigates the interplay between the dispersive response and the relative center-of-mass motion of two ground-…
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…
Equivalence of Stabilizer and Shannon Rényi Entropies: Exact Results for Quantum Critical Chains
E. A. Ramirez Trino, M. A. Rajabpour
Shannon-Rényi and stabilizer entropies are key diagnostics of structure, ``nonstabilizerness,'' phase transitions, and universality in quantum many-body states. We establish an exa…
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…
