Quantum Algorithms for Inverse Participation Ratio Estimation in multi-qubit and multi-qudit systems
Yingjian Liu, Piotr Sierant, Paolo Stornati +2
Inverse Participation Ratios (IPRs) and the related Participation Entropies quantify the spread of a quantum state over a selected basis of the Hilbert space, offering insights int…
Inherent quantum resources in stationary spin chains
Marcin PÅodzieÅ, Jan ChwedeÅczuk, Maciej Lewenstein
The standard way to generate many-body quantum correlations is via a dynamical protocol: an initial product state is transformed by interactions that generate non-classical correla…
Entanglement classification and \emph{non-k}-separability certification via Greenberger-Horne-Zeilinger-class fidelity
Marcin PÅodzieÅ, Jan ChwedeÅczuk, Maciej Lewenstein +1
Many-body quantum systems can be characterised using the notions of \emph{k}-separability and entanglement depth. A quantum state is \emph{k}-separable if it can be expressed as a…
Characterizing out-of-distribution generalization of neural networks: application to the disordered Su-Schrieffer-Heeger model
Kacper CybiÅski, Marcin PÅodzieÅ, MichaÅ Tomza +3
Machine learning (ML) is a promising tool for the detection of phases of matter. However, ML models are also known for their black-box construction, which hinders understanding of…
High Harmonic Tracking of Ultrafast Electron Dynamics across the Mott to Charge Density Wave Phase Transition
Marlena Dziurawiec, Jessica O. de Almeida, Mohit Lal Bera +6
Different insulator phases compete with each other in strongly correlated materials with simultaneous local and non-local interactions. It is known that the homogeneous Mott insula…
