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…
Efficient qudit based scheme for photonic quantum computing
Márton Karácsony, László Oroszlány, Zoltán Zimborás
Linear optics is a promising alternative for the realization of quantum computation protocols due to the recent advancements in integrated photonic technology. In this context usua…
Hybrid Quantum-Classical Autoencoders for End-to-End Radio Communication
Zsolt Tabi, Bence Bakó, Dániel T. R. Nagy +4
Quantum neural networks are emerging as potential candidates to leverage noisy quantum processing units for applications. Here we introduce hybrid quantum-classical autoencoders fo…
Self-consistent quantum measurement tomography based on semidefinite programming
Marco Cattaneo, Matteo A. C. Rossi, Keijo Korhonen +4
We propose an estimation method for quantum measurement tomography (QMT) based on semidefinite programming (SDP), and discuss how it may be employed to detect experimental imperfec…
