No-cost Bell nonlocality certification from quantum tomography and its applications in quantum-magic-resource witnessing
Pawel Cieslinski, Lukas Knips, Harald Weinfurter +1
Tomographic measurements are the standard tool for characterizing quantum states, yet they are usually regarded only as means for state reconstruction or fidelity measurement. Here…

Unmasking the Polygamous Nature of Quantum Nonlocality
PaweÅ CieÅliÅski, Lukas Knips, Mateusz Kowalczyk +4
Quantum mechanics imposes limits on the statistics of certain observables. Perhaps the most famous example is the uncertainty principle. Similar trade-offs also exist for the simul…

Analysing quantum systems with randomised measurements
PaweÅ CieÅliÅski, Satoya Imai, Jan Dziewior +6
Measurements with randomly chosen settings determine many important properties of quantum states without the need for a shared reference frame or calibration. They naturally emerge…
