Exact formula for geometric quantum complexity of cosmological perturbations
Satyaki Chowdhury, Jakub Mielczarek
Nielsen's geometric approach offers a powerful framework for quantifying the complexity of unitary transformations. In this formulation, complexity is defined as the length of the…

Spread and circuit complexity as a measure of particle content and phase space fluctuations
Satyaki Chowdhury
In this work, we investigate the relation between different notions of quantum complexity, namely, circuit and spread complexity and physically meaningful quantities such as the pa…
