Infinite magic and the emergence of the continuum
Leo Shaposhnik, Lorenzo Leone, Lennart Bittel +3
Which features of a quantum state are needed for a relativistic quantum field theory to emerge from a lattice system? We address this question by establishing a quantitative relati…
Nonadditivity in fermionic quantum Shannon theory
Farzin Salek, Amir-Reza Negari, Graeme Smith +2
We study collective state preparation and channel encoding in fermionic systems under parity superselection and composition governed by the canonical anticommutation relations. For…
Approximation theorems for fermionic Gaussian states
Amir-Reza Negari, Farzin Salek, Zoltán Zimborás +3
A recurring principle in many-body physics is that sufficiently distributed interactions or correlations lead to an effectively mean-field description. For fermionic Gaussian state…
Exact Operator Complexity Measures from Random Matchgate Unitaries
Gregory A. L. White, Jens Eisert, Neil Dowling
Matchgate circuits describe classically tractable dynamics in a physically relevant setting while nonetheless exhibiting features characteristic of complex quantum systems, such as…
Dilation theorem for continuum quantum stochastic processes
Jonáš Fuksa, Clara Wassner, Jens Eisert +1
Connecting mathematical formalism in open quantum systems to its underlying physics necessitates the notion of a dilation, a way to bridge stochastic dynamics with deterministic Sc…
Emergent statistical mechanics in holographic random tensor networks
Shozab Qasim, Jens Eisert, Alexander Jahn
Recent years have enjoyed substantial progress in capturing properties of complex quantum systems by means of random tensor networks (RTNs), which form ensembles of quantum states…
