Variational quantum simulation of U(1) lattice gauge theories with qudit systems
Pavel P. Popov, Michael Meth, Maciej Lewenstein +4
Lattice gauge theories are fundamental to various fields, including particle physics, condensed matter, and quantum information theory. Recent progress in the control of quantum sy…
Engineering holography with stabilizer graph codes
Gerard Anglès Munné, Valentin Kasper, Felix Huber
The discovery of holographic codes established a surprising connection between quantum error correction and the anti-de Sitter-conformal field theory correspondence. Recent technol…
Quantum approximate optimization algorithm for qudit systems
Yannick Deller, Sebastian Schmitt, Maciej Lewenstein +5
A frequent starting point of quantum computation platforms are two-state quantum systems, i.e., qubits. However, in the context of integer optimization problems, relevant to schedu…
Non-Abelian gauge invariance from dynamical decoupling
Valentin Kasper, Torsten V. Zache, Fred Jendrzejewski +2
Lattice gauge theories are fundamental to such distinct fields as particle physics, condensed matter or quantum information theory. The recent progress in the control of artificial…
Storage capacity and learning capability of quantum neural networks
Maciej Lewenstein, Aikaterini Gratsea, Andreu Riera-Campeny +3
We study the storage capacity of quantum neural networks (QNNs) described as completely positive trace preserving (CPTP) maps, which act on an -dimensional Hilbert space. We dem…
From the Jaynes-Cummings model to non-Abelian gauge theories: a guided tour for the quantum engineer
Valentin Kasper, Gediminas Juzeliunas, Maciej Lewenstein +2
The design of quantum many body systems, which have to fulfill an extensive number of constraints, appears as a formidable challenge within the field of quantum simulation. Lattice…
