Bounding the entanglement of a state from its spectrum
Jofre Abellanet-Vidal, Guillem Müller-Rigat, Albert Rico +1
We introduce a framework to upper bound the entanglement content of a bipartite quantum state from its spectrum alone. Using linear maps and their inverses, we derive rigorous cons…
Many-body -local ground states as probes for unitary quantum metrology
Majid Hassani, Mengyao Hu, Guillem Müller-Rigat +2
Multipartite quantum states saturating the Heisenberg limit of sensitivity typically require full-body correlators to be prepared. On the other hand, experimentally practical Hamil…
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…
Linear maps as sufficient criteria for entanglement depth and compatibility in many-body systems
Maciej Lewenstein, Guillem Müller-Rigat, Jordi Tura +1
Physical transformations are described by linear maps that are completely positive and trace preserving (CPTP). However, maps that are positive (P) but not completely positive (CP)…
