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…

Absolute separability witnesses for symmetric multiqubit states

Eduardo Serrano-Ensástiga, Jérôme Denis, John Martin

The persistent separability of certain quantum states, known as symmetric absolutely separable (SAS), under symmetry-preserving global unitary transformations is of key significanc…

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…

Estimation of the geometric measure of entanglement with Wehrl Moments through Artificial Neural Networks

Jérôme Denis, François Damanet, John Martin

In recent years, artificial neural networks (ANNs) have become an increasingly popular tool for studying problems in quantum theory, and in particular entanglement theory. In this…

Extreme depolarization for any spin

Jérôme Denis, John Martin

The opportunity to build quantum technologies operating with elementary quantum systems with more than two levels is now increasingly being examined, not least because of the avail…
