Super Quantum Discord with Weak Measurements [PDF]
, 2013 Weak measurements cause small change to quantum states, thereby opening up the possibility of new ways of manipulating and controlling quantum systems. We ask, can weak measurements reveal more quantum correlation in a composite quantum state?

Operational interpretations of quantum discord [PDF]
, 2011 Quantum discord quantifies non-classical correlations going beyond the standard classification of quantum states into entangled and unentangled ones. Although it has received considerable attention, it still lacks any precise interpretation in terms of ...

Maximizing quantum discord from interference in multi-port fiber beamsplitters
npj Quantum Information, 2021 Fourth-order interference is an information processing primitive for photonic quantum technologies, as it forms the basis of photonic controlled-logic gates, entangling measurements, and can be used to produce quantum correlations.
