Quantum Discord vs Entanglement — Bipartite Qubit State

For a 2-qubit state parameterized by mixing p and correlations c, explore total mutual info I(A:B), classical correlations J, and quantum discord D = I − J. Discord captures quantum correlations beyond entanglement.

S(ρ) = — | S(A) = — | I(A:B) = — | J (classical) = — | Discord D = —
