Many-body Hierarchy of Dissipative Timescales in a Quantum Computer

Oscar Emil Sommer, Francesco Piazza, David J. Luitz

We show that current noisy quantum computers are ideal platforms for the simulation of quantum many-body dynamics in generic open systems. We demonstrate this using the IBM Quantum…

Multimode-polariton superradiance via Floquet engineering

Christian Høj Johansen, Johannes Lang, Andrea Morales +3

We consider an ensemble of ultracold bosonic atoms within a near-planar cavity, driven by a far detuned laser whose phase is modulated at a frequency comparable to the transverse c…

Imaging the interface of a qubit and its quantum-many-body environment

S. Rammohan, S. Tiwari, A. Mishra +5

Decoherence affects all quantum systems, natural or artificial, and is the primary obstacle impeding quantum technologies. We show theoretically that for a Rydberg qubit in a Bose…

Linear and logarithmic entanglement production in an interacting chaotic system

Sanku Paul, Arnd Bäcker

We investigate entanglement growth for a pair of coupled kicked rotors. For weak coupling, the growth of the entanglement entropy is found to be initially linear followed by a loga…

Quantum entanglement recognition

Jun Yong Khoo, Markus Heyl

Entanglement constitutes a key characteristic feature of quantum matter. Its detection, however, still faces major challenges. In this letter, we formulate a framework for probing…

Random multipolar driving: tunably slow heating through spectral engineering

Hongzheng Zhao, Florian Mintert, Roderich Moessner +1

Driven quantum systems may realize novel phenomena absent in static systems, but driving-induced heating can limit the time-scale on which these persist. We study heating in intera…
