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…

Fast classical simulation algorithms for free-fermion dynamics with magic input

Jiwon Heo, Oliver Reardon-Smith, Michał Oszmaniec +2

The classical cost of simulating free-fermion (matchgate) circuits depends on both the input state and the computational task. We develop classical algorithms for circuits with non…

Higher-order quantum thermodynamics: equilibrium and causal structure

Simon Milz, Kyrylo Simonov, Zoltán Zimborás +3

Quantum thermodynamics is traditionally formulated as a theory of equilibrium states and state transformations. Recent advances in higher-order quantum transformations, which descr…

Overlapping qubits from non-isometric maps and de Sitter tensor networks

ChunJun Cao, Wissam Chemissany, Alexander Jahn +1

We construct approximately local observables, or "overlapping qubits", using non-isometric maps and show that processes in local effective theories can be spoofed with a quantum sy…
