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…
Universal quantum computation and quantum error correction with ultracold atomic mixtures
Valentin Kasper, Daniel González-Cuadra, Apoorva Hegde +7
Quantum information platforms made great progress in the control of many-body entanglement and the implementation of quantum error correction, but it remains a challenge to realize…
Fate of Lattice Gauge Theories Under Decoherence
Jad C. Halimeh, Valentin Kasper, Philipp Hauke
A major test of the capabilities of modern quantum simulators and NISQ devices is the reliable realization of gauge theories, which constitute a gold standard of implementational e…
Preparation of the 1/2-Laughlin state with atoms in a rotating trap
Bárbara Andrade, Valentin Kasper, Maciej Lewenstein +2
Fractional quantum Hall systems are among the most exciting strongly correlated systems. Accessing them microscopically via quantum simulations with ultracold atoms would be an imp…
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…
