Path Integral Approach to Quantum Fisher Information
Francis J. Headley, Mahdi RouhbakhshNabati, Henry Harper-Gardner +3
We present a real-time path-integral formulation of the quantum Fisher information for dynamical parameter estimation. For pure states undergoing unitary evolution, we show that th…
Semiclassical Approach to Quantum Fisher Information
Mahdi RouhbakhshNabati, Daniel Braun, Henning Schomerus
Quantum sensors driven into the quantum chaotic regime can have dramatically enhanced sensitivity, which, however, depends intricately on the details of the underlying classical ph…
Spectral chaos bounds from scaling theory of maximally efficient quantum-dynamical scrambling
Tara Kalsi, Alessandro Romito, Henning Schomerus
A key conjecture about the evolution of complex quantum systems towards an ergodic steady state, known as scrambling, is that this process acquires universal features when it is mo…
