Universality in fidelity-based quantum metrology
Luis Aragón-Muñoz, Chryssomalis Chryssomalakos, Ana Gabriela Flores-Delgado +2
We consider the problem of identifying the quantum spin states that are the optimal sensors of a given transformation, averaged over all possible orientations of the spin system. O…
Multiqubit monogamy relations beyond shadow inequalities
Eduardo Serrano-Ensástiga, Olivier Giraud, John Martin
Multipartite quantum systems are subject to monogamy relations that impose fundamental constraints on the distribution of quantum correlations between subsystems. These constraints…
Dynamical decoupling of interacting spins through group factorization
Colin Read, Eduardo Serrano-Ensástiga, John Martin
Dynamical decoupling (DD) is a well-known open-loop protocol for suppressing unwanted interactions in a quantum system, thereby drastically extending the coherence time of useful q…
