Complexity of mixed states in QFT and holography

E Caceres, S Chapman, JD Couch… - Journal of High Energy …, 2020 - Springer
A bstract We study the complexity of Gaussian mixed states in a free scalar field theory using
the 'purification complexity'. The latter is defined as the lowest value of the circuit complexity …
