Naimark's dilation theorem

Witryna13 lip 2024 · A recent generalization 10 of Naimark’s dilation theorem 11 showed that the most general measurement on N qubits requires N auxiliary qubits, when projective measurements can be implemented on ... Witryna14 gru 2012 · By virtue of Naimark's dilation theorem, any POVM can always be realized with a suitable coupling between the system and an auxiliary system and by performing a projective measurement on the joint system. In practice, finding the appropriate coupling is rather nontrivial. Here we propose an experimental design for …

WitrynaAn extension of the Naimark dilation theorem to free semigroups is considered. This is used to construct a large class of positive definite operator-valued kernels on the unital free semigroup on n generators and to study the class Cρ (ρ>0) of ρ-contractive sequences of operators. The dilation theorems are also used to extend the … Witryna20 kwi 2024 · In operator theory, Naimark's dilation theorem is a result that characterizes positive operator valued measures.
