Geometric approach to extend Landau-Pollak uncertainty relations for positive operator-valued measures

Mostrar todas las versiones(2)

We provide a twofold extension of Landau-Pollak uncertainty relations for mixed quantum states and for positive operator-valued measures, by recourse to geometric considerations. The generalization is based on metrics between pure states, having the form of a function of the square of the inner prod...
