Uncertainty related to position and momentum localization of a quantum state
Uncertainty related position momentum localization quantum state
2010/11/5
This paper presents the uncertainty related to position and momentum localization of a quantum state in terms of entropic uncertainty relations. We slightly improve the inequality given in [Phys. Rev....
Insecurity of position-based quantum cryptography protocols against entanglement attacks
Insecurity position-based quantum cryptography protocols entanglement attacks
2010/10/19
Recently, position-based quantum cryptography has been claimed to be unconditionally secure.
On the contrary, here we show that the existing proposals for position-based quantum cryptography are, in ...
Sub-wavelength position measurements with running wave driving fields
Sub-wavelength position measurements running wave driving fields
2010/4/12
A scheme for sub-wavelength position measurements of quantum particles is discussed, which operates with running-wave laser fields as opposed to standing wave fields proposed in previous setups. The p...
