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)…

Robustness of non-locality in many-body open quantum systems

Carlo Marconi, Andreu Riera-Campeny, Anna Sanpera +1

Non-locality consists in the existence of non-classical correlations between local measurements. So far, it has been investigated mostly in isolated quantum systems. Here we show t…

The role of coherence theory in attractor quantum neural networks

Carlo Marconi, Pau Colomer Saus, María García Díaz +1

We investigate attractor quantum neural networks (aQNNs) within the framework of coherence theory. We show that: i) aQNNs are associated to non-coherence-generating quantum channel…

Volumes of parent Hamiltonians for benchmarking quantum simulators

María García Díaz, Gael Sentís, Ramon Muñoz-Tapia +1

We investigate the relative volume of parent Hamiltonians having a target ground state up to some fixed error , a quantity which sets a benchmark on the performance of quantum s…

Open quantum systems coupled to finite baths: A hierarchy of master equations

Andreu Riera-Campeny, Anna Sanpera, Philipp Strasberg

An open quantum system in contact with an infinite bath approaches equilibrium, while the state of the bath remains unchanged. If the bath is finite, the open system still relaxes…

Entangled symmetric states and copositive matrices

Carlo Marconi, Albert Aloy, Jordi Tura +1

Entanglement in symmetric quantum states and the theory of copositive matrices are intimately related concepts. For the simplest symmetric states, i.e., the diagonal symmetric (DS)…
