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…
The sum of entanglement and subsystem coherence is invariant under quantum reference frame transformations
Carlo Cepollaro, Ali Akil, Paweł Cieśliński +2
Recent work on quantum reference frames (QRFs) has demonstrated that superposition and entanglement are properties that change under QRF transformations. Given their utility in qua…
Exploring Many-body Interactions Through Quantum Fisher Information
Paweł Cieśliński, Paweł Kurzyński, Tomasz Sowiński +2
The investigation of many-body interactions holds significant importance in both quantum foundations and information. Hamiltonians coupling multiple particles at once, beyond other…
Unmasking the Polygamous Nature of Quantum Nonlocality
Paweł Cieśliński, 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
Paweł Cieśliński, 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…
The fastest generation of multipartite entanglement with natural interactions
Paweł Cieśliński, Waldemar Kłobus, Paweł Kurzyński +2
Natural interactions among multiple quantum objects are fundamentally composed of two-body terms only. In contradistinction, single global unitaries that generate highly entangled…
Valid and efficient entanglement verification with finite copies of a quantum state
Pawel Cieslinski, Jan Dziewior, Lukas Knips +5
Detecting entanglement in multipartite quantum states is an inherently probabilistic process, typically with a few measured samples. The level of confidence in entanglement detecti…
Gaussian state entanglement witnessing through lossy compression
Waldemar Klobus, Pawel Cieslinski, Lukas Knips +2
We propose a method to witness entanglement between two continuous-variable systems in a Gaussian state. Its key ingredient is a local lossy state transfer from the original spatia…
