Detecting mixedness of qutrit systems using the uncertainty relation
S. Mal, T. Pramanik, A. S. Majumdar
We show that the uncertainty relation as expressed in the Robertson-Schrodinger generalized form can be used to detect the mixedness of three-level quantum systems in terms of meas…

The role of quantum discord in reduction of the lower bound of entropic uncertainty relation in presence of quantum memory
T. Pramanik, S. Mal
The uncertainty of measurement on a quantum system can be reduced in presence of quantum memory [M. Berta et. al. Nature Phys. {\bf 6}, 659 (2010)]. By measurement on quantum memor…
