Categorical characterizations of operator-valued measures [PDF]
Electronic Proceedings in Theoretical Computer Science, 2014 The most general type of measurement in quantum physics is modeled by a positive operator-valued measure (POVM). Mathematically, a POVM is a generalization of a measure, whose values are not real numbers, but positive operators on a Hilbert space.

Magic informationally complete POVMs with permutations [PDF]
Royal Society Open Science, 2017 Eigenstates of permutation gates are either stabilizer states (for gates in the Pauli group) or magic states, thus allowing universal quantum computation (Planat, Rukhsan-Ul-Haq 2017 Adv. Math. Phys. 2017, 5287862 ( doi:10.1155/2017/5287862 )). We show in this paper that a subset of such magic states, when acting on

Positive operator valued measures and the quantum Monty Hall problem
Anais da Academia Brasileira de Ciências, 2006 A quantum version of the Monty Hall problem, based upon the Positive Operator Valued Measures (POVM) formalism, is proposed. It is shown that basic normalization and symmetry arguments lead univocally to the associated POVM elements, and that the ...

Minimal sufficient positive-operator valued measure on a separable Hilbert space [PDF]
, 2015 We introduce a concept of a minimal sufficient positive-operator valued measure (POVM), which is the least redundant POVM among the POVMs that have the equivalent information about the measured quantum system.

Uncertainty Relations for Positive Operator Valued Measures [PDF]
, 2007 How much unavoidable randomness is generated by a Positive Operator Valued Measure (POVM)? We address this question using two complementary approaches. First we study the variance of a real variable associated to the POVM outcomes.

Reconstruction of coherence matrix in x-representation using nonclassical Hartmann sensor [PDF]
EPJ Web of Conferences, 2022 We show the coherence properties of a signal can be measured by a Hartmann wavefront sensor in a nonclassical regime. Recasting the detection theory of the classical Hartmann sensor in the sense of quantum tomography enables to measure the coherence ...

Symmetric Informationally Complete Quantum Measurements [PDF]
, 2003 We consider the existence in arbitrary finite dimensions d of a POVM comprised of d^2 rank-one operators all of whose operator inner products are equal. Such a set is called a ``symmetric, informationally complete'' POVM (SIC-POVM) and is equivalent to a
