Measurement - induced qudit geometric discord

22 May 2017  ·  Lugiewicz Piotr, Frydryszak Andrzej, Jakobczyk Lech ·

We study the measurement-induced geometric discord based on the trace norm and generalize some properties known for qutrits to qudits. Previous preliminary results for bipartite qutrit systems (i.e. d=3 systems) are here strictly proved for arbitrary d. Present study supports observations, coming also from other approaches, that systems with $d \geq 3$ show similar behaviour when quantum correlations are concerned, but there is pronounced difference between d=2 and d=3... Qubit systems are exceptionally simple. Underlying geometry of state spaces and related Lie groups are responsible for that. read more
