Designing locally maximally entangled quantum states with arbitrary local symmetries
Oskar Słowik, Adam Sawicki, Tomasz Maciążek
One of the key ingredients of many LOCC protocols in quantum information is a multiparticle (locally) maximally entangled quantum state, aka a critical state, that possesses local…
A link between symmetries of critical states and the structure of SLOCC classes in multipartite systems
Oskar Słowik, Martin Hebenstreit, Barbara Kraus +1
Central in entanglement theory is the characterization of local transformations among pure multipartite states. As a first step towards such a characterization, one needs to identi…
Implications of pinned occupation numbers for natural orbital expansions. II: Rigorous derivation and extension to non-fermionic systems
Tomasz Maciążek, Adam Sawicki, David Gross +2
We have explained and comprehensively illustrated in Part I that the generalized Pauli constraints suggest a natural extension of the concept of active spaces. In the present Part…
Implications of pinned occupation numbers for natural orbital expansions. I: Generalizing the concept of active spaces
Christian Schilling, Carlos L. Benavides-Riveros, Alexandre Lopes +2
The concept of active spaces simplifies the description of interacting quantum many-body systems by restricting to a neighbourhood of active orbitals around the Fermi level. The re…
Asymptotic properties of entanglement polytopes for large number of qubits
Tomasz Maciążek, Adam Sawicki
Entanglement polytopes have been recently proposed as the way of witnessing the SLOCC multipartite entanglement classes using single particle information. We present first asymptot…
Are Scattering Properties of Graphs Uniquely Connected to Their Shapes?
Oleh Hul, Michał Ławniczak, Szymon Bauch +3
The famous question of Mark Kac "Can one hear the shape of a drum?" addressing the unique connection between the shape of a planar region and the spectrum of the corresponding Lapl…
