Improving the dynamics of quantum sensors with reinforcement learning
Jonas Schuff, Lukas J. Fiderer, Daniel Braun
Recently proposed quantum-chaotic sensors achieve quantum enhancements in measurement precision by applying nonlinear control pulses to the dynamics of the quantum sensor while usi…
Maximal Quantum Fisher Information for Mixed States
Lukas J. Fiderer, Julien M. E. Fraïsse, Daniel Braun
We study quantum metrology for unitary dynamics. Analytic solutions are given for both the optimal unitary state preparation starting from an arbitrary mixed state and the correspo…
A quantum-chaotic cesium-vapor magnetometer
Lukas J. Fiderer, Daniel Braun
Quantum-enhanced measurements represent the path towards the best measurement precision allowed by the laws of quantum mechanics. Known protocols usually rely on the preparation of…
