Optimal control of a quantum sensor: A fast algorithm based on an analytic solution

S. Hernández-Gómez, F. Balducci, G. Fasiolo +3

Quantum sensors can show unprecedented sensitivities, provided they are controlled in a very specific, optimal way. Here, we consider a spin sensor of time-varying fields in the pr…

Learning the noise fingerprint of quantum devices

Stefano Martina, Lorenzo Buffoni, Stefano Gherardini +1

Noise sources unavoidably affect any quantum technological device. Noise's main features are expected to strictly depend on the physical platform on which the quantum device is rea…

Remote Phase Sensing by Coherent Single Photon Addition

Nicola Biagi, Saverio Francesconi, Manuel Gessner +2

We propose a remote phase sensing scheme inspired by the high sensitivity of the entanglement produced by coherent multimode photon addition on the phase set in the remote heraldin…
