Query: Sharma-Mittal Quantum Discord   We demonstrate a generalization of quantum discord using a generalized
definition of von-Neumann entropy, which is Sharma-Mittal entropy; and the new
definition of discord is called Sharma-Mittal quantum discord. Its analytic
expressions are worked out for two qubit quantum states as well as Werner,
isotropic, and pointer states as special cases. The R{\'e}nyi, Tsallis, and
von-Neumann entropy based quantum discords can be expressed as limiting cases
for of Sharma-Mittal quantum discord. We also numerically compare all these
discords and entanglement negativity.
