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…
Bose-Einstein condensation in exotic lattice geometries
Kamil Dutkiewicz, Marcin PÅodzieÅ, Abel Rojo-Francà s +3
Modern quantum engineering techniques allow for synthesizing quantum systems in exotic lattice geometries, from self-similar fractal networks to negatively curved hyperbolic graphs…
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…
Transfer of quantum-enhanced information through a many-body system
Piotr Wysocki, Marcin PÅodzieÅ, Jan ChwedeÅczuk
Forthcoming quantum devices will require high-fidelity information transfer across a many-body system. We formulate the criterion for lossless signal propagation and show that a si…
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…
String breaking dynamics in Ising chain with local vibrations
Arindam Mallick, Maciej Lewenstein, Jakub Zakrzewski +1
We consider the dynamics in the one-dimensional quantum Ising model in which each spin coherently interacts with its phononic mode. The model is motivated by quantum simulators bas…
