Nearly Heisenberg-limited noise-unbiased frequency estimation by tailored sensor design
Francisco Riberi, Gerardo Paz-Silva, Lorenza Viola
We consider entanglement-assisted frequency estimation by Ramsey interferometry, in the presence of dephasing noise from spatiotemporally correlated environments.By working in the…

Resource-efficient digital characterization and control of classical non-Gaussian noise
Wenzheng Dong, Gerardo A. Paz-Silva, Lorenza Viola
We show the usefulness of frame-based characterization and control [PRX Quantum 2, 030315 (2021)] for non-Markovian open quantum systems subject to classical non-Gaussian dephasing…
