Harnessing quantum back-action for time-series processing
Giacomo Franceschetto, Marcin PÅodzieÅ, Maciej Lewenstein +2
Quantum measurements affect the state of the observed systems via back-action. While projective measurements extract maximal classical information, they drastically alter the syste…
Quantifying superluminal signalling in Schrödinger-Newton model
Julia OsÄka-Lenart, Marcin PÅodzieÅ, Maciej Lewenstein +1
The Schrödinger-Newton equation aims at describing the dynamics of massive quantum systems subject to the gravitational self-interaction. As a deterministic nonlinear quantum wave…
Many-body quantum resources of graph states
Marcin PÅodzieÅ, Maciej Lewenstein, Jan ChwedeÅczuk
Characterizing the non-classical correlations of a complex many-body system is an important part of quantum technologies. A versatile tool for such a task is one that scales well w…
Boosting thermalization of classical and quantum many-body systems
Jin-Fu Chen, Kshiti Sneh Rai, Patrick Emonts +5
Understanding and optimizing the relaxation dynamics of many-body systems is essential both for foundational studies in quantum thermodynamics and for applications such as quantum…
Quantum Machine Learning in Multi-Qubit Phase-Space Part I: Foundations
Timothy Heightman, Edward Jiang, Ruth Mora-Soto +2
Quantum machine learning (QML) seeks to exploit the intrinsic properties of quantum mechanical systems, including superposition, coherence, and quantum entanglement for classical d…
Nonperturbative signatures of fractons in the twisted multiflavor Schwinger Model
Pavel P. Popov, Valentin Kasper, Maciej Lewenstein +3
Gauge-field configurations with nontrivial topology have profound consequences for the physics of Abelian and non-Abelian gauge theories. Over time, arguments have been gathering f…
