Entanglement asymmetry in CFT and its relation to non-topological defects
The entanglement asymmetry is an information based observable that quantifies the degree of symmetry breaking in a region of an extended quantum...

No second law of entanglement manipulation after all
Many fruitful analogies have emerged between the theories of quantum entanglement and thermodynamics, motivating the pursuit of an axiomatic...

Entanglement asymmetry in the ordered phase of many-body systems: the Ising field theory
Global symmetries of quantum many-body systems can be spontaneously broken. Whenever this mechanism happens, the ground state is degenerate and one...

Entanglement and U(D)-spin squeezing in symmetric multi-quDit systems and applications to quantum phase transitions in Lipkin–Meshkov–Glick D-level atom models
Collective spin operators for symmetric multi-quDit (namely identical D -level atom) systems generate a U( D ) symmetry. We explore generalizations to...

Enhancing entanglement of assistance using weak measurement and quantum measurement reversal in correlated amplitude dam** channel
Entanglement of assistance from multipartite to fewer partites (e.g., bipartite) entangled state via measurements is an important way for generating...
