All non-Gaussian states are advantageous for channel discrimination: Robustness of non-convex continuous variable quantum resources
Leah Turner, Madalin Guta, Gerardo Adesso
Which quantum phenomena are advantageous for information processing tasks? By classifying quantum states as resourceful versus non-resourceful, or free, the mathematical formalism…

Unambiguous measurement in an unshielded microscale magnetometer with sensitivity below 1 pT/rHz
Hamish A. M. Taylor, Christopher C. Bounds, Alex Tritt +1
Cold atom magnetometers exploit a dense ensemble of quanta with long coherence times to realise leading sensitivity on the micrometer scale. Configured as a Ramsey interferometer,…
