Monogamy of Entanglement — CKW Tangle Conservation (2D)

Interactive 2D demo of the Coffman-Kundu-Wootters monogamy of entanglement: mix a GHZ and W three-qubit state, watch a from-scratch partial-trace + Wootters-concurrence engine compute real pairwise and one-vs-rest tangles, and verify the CKW inequality live — including across thousands of random states.

Entanglement is a shared resource, and it turns out to be a jealous one: a qubit cannot be maximally entangled with two partners at once. This 2D canvas engine builds a genuine 8-amplitude three-qubit pure state, computes real reduced density matrices by partial trace, extracts real Wootters concurrence via a from-scratch eigenvalue solver, and verifies live — including across thousands of random states — that the Coffman-Kundu-Wootters monogamy inequality τ(AB)+τ(AC) ≤ τ(A|BC) never breaks.

⚙ Under the hood

Redistribute a shared excitation across three qubits and watch the Coffman-Kundu-Wootters monogamy inequality hold exactly: entangling qubit A more with B always dims its entanglement with C by precisely that much.
