Dephrasure channel and superadditivity of coherent information

The quantum capacity of a quantum channel captures its capability for noiseless quantum communication. It lies at the heart of quantum information theory.

Untangling entanglement and chaos

How does classical chaos affect the generation of quantum entanglement? What signatures of chaos exist at the quantum level and how can they be quantified?

Correlations with subsystem constraints

A quantum channel with correlations among only certain subsystems can be viewed as a "correlation with subsystem constraints".

An operational toy model for quantum causality (in finite topological spaces) using coloring rules

In the quest for quantum gravity Hardy suggests the radical aspects of quantum physics (probabilistic nature) and relativity (dynamic causality) would manifest together.

Deterministic global ontologies for quantum systems

Epistemic models of nature prove to be problematic in many settings, particularly in those for which measurement procedures are ill-defined.
