Web15 nov. 2024 · This is the definition we will use. Two qubits are entangled when they are maximally correlated. And this means that when we measure qubit one to be, say, 0 then qubit two is also 0. When we measure qubit one to be 1 then the second qubit is also 1, no matter what – they are maximally correlated. http://research.physics.illinois.edu/QI/Photonics/papers/My%20Collection.Data/PDF/Maximally%20Entangled%20Mixed%20States%20Creation%20and%20Concentration.pdf borgo corse planWebNonlocality and quantum entanglement constitute two special aspects of the quantum correlations existing in quantum systems, which are of paramount importance in quantum-information theory.
