Entanglement classification and \emph{non-k}-separability certification via Greenberger-Horne-Zeilinger-class fidelity
Marcin Płodzień, Jan Chwedeńczuk, Maciej Lewenstein +1
Many-body quantum systems can be characterised using the notions of \emph{k}-separability and entanglement depth. A quantum state is \emph{k}-separable if it can be expressed as a…
Introduction to quantum entanglement in many-body systems
Anubhav Kumar Srivastava, Guillem Müller-Rigat, Maciej Lewenstein +1
The quantum mechanics formalism introduced new revolutionary concepts challenging our everyday perceptions. Arguably, quantum entanglement, which explains correlations that cannot…
Metrological robustness of high photon number optical cat states
Philipp Stammer, Tomás Fernández Martos, Maciej Lewenstein +1
In the domain of quantum metrology, cat states have demonstrated their utility despite their inherent fragility with respect to losses. Here, we introduce noise robust optical cat…
Enhancing quantum state tomography via resource-efficient attention-based neural networks
Adriano Macarone Palmieri, Guillem Müller-Rigat, Anubhav Kumar Srivastava +3
Resource-efficient quantum state tomography is one of the key ingredients of future quantum technologies. In this work, we propose a new tomography protocol combining standard quan…
