Explore a 57-minute physics lecture where Prof. Adam Bednorz from the Institute of Theoretical Physics at the University of Warsaw delves into the verification of quantum resources through null witnessing. Learn how determinant probabilities in measurement protocols can verify systems of limited dimension, examining both single-system prepare-and-measure scenarios and bipartite system scenarios with independent parties. Discover the results of applying these protocols to public quantum computing providers including IBM Quantum, IQM Resonance, and IonQ, revealing inconsistencies in the basic qubit model and suggesting contributions from extra dimensional spaces beyond standard technical issues. Examine findings that show failures in no-signaling tests, particularly in IBM Quantum systems, presented as part of the Warsaw colloquium for theoretical physics at CTP PAS.
