Uncertainty Relation Revisited from Quantum Estimation Theory
Uncertainty Relation Revisited Quantum Estimation Theory
2010/11/5
By invoking quantum estimation theory we formulate the uncertainty relation for arbitrary quantum states and measurements in a finite-dimensional Hilbert space. To obtain information about the quantum...

On quantum estimation quantum cloning finite quantum de Finetti theorems
2010/11/4
This paper presents a series of results on the interplay between quantum estimation, cloning and finite de Finetti theorems. First, we consider the measure-and-prepare channel that uses optimal estim...
