    "abstract": "In a system of n quantum particles, we define a measure of the degree of\nirreducible n-way correlation, by which we mean the correlation that cannot be\naccounted for by looking at the states of (n-1) particles. In the case of\nalmost all pure states of three qubits we show that there is no such\ncorrelation: almost every pure state of three qubits is completely determined\nby its two-particle reduced density matrices.",
