The original definition of quantum discord of bipartite states was defined under pro jective measurements.
Generalizations of Quantum Discord
In this letter we generalize it in two ways: one is we define the quantum discord as the minimal loss of conditional entropy under all one-side general measurements; the other is similar with the original case but we perform the pro jective measurements on an extended infinite dimensional Hilbert space.
Generalizations of Quantum Discord
We prove some inequalities about different quantum discords, and also derive an equality which relates one of these quantum discords and entanglement of formation (EOF).
Generalizations of Quantum Discord
Finally, a definition of the quantum discord under two-side measurements is given.
Generalizations of Quantum Discord
However, entanglement is not the only type of correlation useful for quantum technology. A different notion of measure, quantum discord, has also been proposed to characterize quantum correlation based on quantum measurements [3, 4].
Generalizations of Quantum Discord
Quantum discord captures the nonlocal correlation more general than entanglement, it can exist in some states even if entanglement does vanish.
Generalizations of Quantum Discord
Recently, quantum discord has received much more attention.
Generalizations of Quantum Discord
Its evaluation involves optimization procedure, and analytical expressions are known only in a few cases [8, 9]. A witness of quantum discord for 2 × n states was found, while we have known that almost all quantum states have nonvanishing quantum discord .
Generalizations of Quantum Discord
Also, the characteristics of quantum discord in some physical models and in information processing have been studied [16–18].
Generalizations of Quantum Discord
The original definition of quantum discord was defined under pro jective measurements, in this letter, we give some generalizations of it.
Generalizations of Quantum Discord
This is meaningful not only in mathematics but also in physics since through the generalizations we will get a more fundamental understanding about quantum discord.
