Charged Complexity and the Thermofield Double State
Shira Chapman, Hong Zhe Chen
We establish a systematic framework for studying quantum computational complexity of Gaussian states of charged systems based on Nielsen's geometric approach. We use this framework…

Complexity of Mixed States in QFT and Holography
Elena Caceres, Shira Chapman, Josiah D. Couch +3
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 complex…
