Supermaps

[Cecila Dammrich]

Quantum supermaps are transformations of quantum processes, and have found many applications in quantum foundations and quantum information theory in the past two decades, particularly in the study of causality. Whilst the concept of a supermap is a simple and intuitive one, the current state-of-the-art formalisations of supermaps cannot be applied to arbitrary Hilbert spaces or Operational Probabilistic Theories (OPTs). We review the standard approaches to defining supermaps in quantum theor...
