Holographic quantum codes with trapped ions
Alex Steiner, Gerard Anglès Munné, Robert Freund +9
Holography is a central concept at the intersection of gravity, condensed matter theory, and quantum information, linking the interior bulk of a system to its boundary. A model rea…
Non-Abelian String-Breaking Dynamics on a Qudit Quantum Computer
Manuel John, Keshav Pareek, Peter Tirler +7
Gauge theories form the foundation of the Standard Model of particle physics. These theories can exhibit confinement, where charged particles only occur in bound states, connected…
Device-independent quantum memory certification in two-point measurement experiments
Leonardo S. V. Santos, Peter Tirler, Michael Meth +6
Quantum memories are key components of emerging quantum technologies. They are designed to store quantum states and retrieve them on demand without losing features such as superpos…
Experimental verification of multi-copy activation of genuine multipartite entanglement
Robert Stárek, Tim Gollerthan, Olga Leskovjanová +5
A central concept in quantum information processing is genuine multipartite entanglement (GME), a type of correlation beyond biseparability, that is, correlations that cannot be ex…
Robust certification of non-projective measurements: theory and experiment
Raphael Brinster, Peter Tirler, Shishir Khandelwal +7
Determining the conditions under which positive operator-valued measures (POVMs), the most general class of quantum measurements, outperform projective measurements remains a chall…
Simulating 2D lattice gauge theories on a qudit quantum computer
Michael Meth, Jan F. Haase, Jinglei Zhang +11
Particle physics underpins our understanding of the world at a fundamental level by describing the interplay of matter and forces through gauge theories. Yet, despite their unmatch…
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…
