A fermionic de Finetti theorem
C. Krumnow, Z. Zimboras, J. Eisert
Quantum versions of de Finetti's theorem are powerful tools, yielding conceptually important insights into the security of key distribution protocols or tomography schemes and allo…
Universal extensions of restricted classes of quantum operations
Michał Oszmaniec, Zoltán Zimborás
For numerous applications of quantum theory it is desirable to be able to apply arbitrary unitary operations on a given quantum system. However, in particular situations only a sub…
Precision bounds for gradient magnetometry with atomic ensembles
Iagoba Apellaniz, Inigo Urizar-Lanz, Zoltan Zimboras +2
We study gradient magnetometry with an ensemble of atoms with arbitrary spin. We calculate precision bounds for estimating the gradient of the magnetic field based on the quantum F…
