There is more to quantum interferometry than entanglement by Bromley, Thomas R., Silva, Isabela A., Oncebay-Segura, Charlie O., Soares-Pinto, Diogo O., deAzevedo, Eduardo R., Tufarelli, Tommaso, Adesso, Gerardo

“…We then prove that the interferometric power can never increase when local commutativity-preserving operations are applied to qubit probes, an important step to validate such a quantity as a genuine quantum correlations monotone. These findings are accompanied by a room-temperature nuclear magnetic resonance experimental investigation, in which two-qubit states with extremal (maximal and minimal) interferometric power at fixed entanglement are produced and characterized.…”

Quantum vector magnetometry based on the Voigt effect by Pyragius, Tadas

“…Our scheme requires only one frequency of modulation and has a simple single axis beam geometry making it advantageous for miniature magnetic field sensors. Furthermore, we extend our Voigt effect scheme to dressed microwave spectroscopy and show that it can be used to infer the prepared state populations paving the way towards partial quantum state tomography.…”
