Geometric formulation of the uncertainty principle
(2014)
A geometric approach to formulate the uncertainty principle between quantum observables acting on an N-dimensional Hilbert space is proposed. We consider the fidelity between a density operator associated with a quantum ...
Effects of magnetic field gradients on the aggregation dynamics of colloidal magnetic nanoparticles
(2015)
We have used low-field 1H nuclear-magnetic resonance (NMR) spectroscopy and molecular dynamics (MD) to investigate the aggregation dynamics of magnetic particles in ionic ferrofluids (IFFs) in the presence of magnetic field ...
Geometric approach to extend Landau-Pollak uncertainty relations for positive operator-valued measures
(2014)
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 ...
Problem of quantifying quantum correlations with non-commutative discord
(2017)
In this work we analyze a non-commutativity measure of quantum correlations recently proposed by Y. Guo [Sci. Rep. 6, 25241 (2016)]. By resorting to a systematic survey of a two-qubit system, we detected an undesirable ...
