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…
