We derive analytic formulas for the geometric measure of quantum discord introduced by Dakic, Vedral, and Brukner for pure states and $(2{\times}n)$-dimensional states and establish a general lower bound for arbitrary states.
Keywords: quantum correlation, quantum discord, geometric measure of quantum discord, interlacing theorem for eigenvalues.
