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…
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…
An Error-aware and Adaptive Method for the Estimation of Quantum Observables on Qudit-Based Quantum Computers
Rick P. A. Simon, Michael Meth, Francesco Martini +4
The accurate estimation of observables is a crucial task in quantum computing. Recent advances have highlighted the need for (a) specialized protocols for qudit-based devices, that…
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…
