Total, quantum, and classical measures of anticoherence for mixed spin states
Jérôme Denis, Tara Lacaille, John Martin +1
Anticoherent spin states have isotropic low-order spin moments and are relevant to direction-independent metrology and quantum reference-frame alignment. In contrast to pure states…

Coherent Generation and Protection of Anticoherent Spin States
Jérôme Denis, Colin Read, John Martin
We report the first protocol specifically designed to generate anticoherent spin- states at different orders. The protocol consists of cycles of a rotation pulse about an axis f…

Polytopes of Absolutely Wigner Bounded Spin States
Jérôme Denis, Jack Davis, Robert B. Mann +1
Quasiprobability has become an increasingly popular notion for characterising non-classicality in quantum information, thermodynamics, and metrology. Two important distributions wi…
