Converting coherence based on positive-operator-valued measures into entanglement

چکیده

Quantum resource theories provide a diverse and powerful framework for extensively studying the phenomena in quantum physics. coherence, resource, is basic ingredient many information tasks. It subject of broad current interest information, new concepts have been introduced generalized since its establishment. Here we show that block coherence can be transformed into entanglement via block-incoherent operation. Moreover, find based on positive-operator-valued measures (POVMs) associated with through Naimark extension acts as potential from perspective generating entanglement. Finally, discuss avenues creating POVM-based present strategies require embedding channels auxiliary systems, give some examples, generalize them.

Positive Operator Valued Measures: A General Setting for Frames

This paper presents an overview of close parallels that exist between the theory of positive operator-valued measures (POVMs) associated with a separable Hilbert space and the theory of frames on that space, including its most important generalizations. The concept of a framed POVM is introduced, and classical frames, fusion frames, generalized frames, and other variants of frames are all shown...

Positive operator valued measures and the quantum Monty Hall problem.

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 classical probabilities associated with the Monty Hall scenario are recovered for a natural choice of the measurement operators.
