Any two-qubit state has nonzero quantum discord under global unitary operations

Quantum discord is significant in analyzing quantum nonclassicality beyond the paradigm of entanglement. Presently we have explored effectiveness global unitary operations manifesting from a general two qubit zero state. Apart emergence some obvious concepts such as absolute classical-quantum, quantum-classical states, more interestingly, it observed that set states characterized by absoluteness contains only maximally mixed Consequently this marks peak purview arbitrary state when other standard methods fail to do so. Set effective unitaries has been provided context. Our observations direct implications remote preparation task.
