🔗 Entanglement Swapping

Watch two independent Bell pairs (A-B and C-D) become entangled with each other (A-D) after a Bell-basis measurement on the middle two qubits — a real 4-qubit statevector simulation of a basic quantum repeater link, with no direct A-D interaction ever taking place.

⚙ Under the hood

Prepare two Bell pairs (A-B and C-D) and perform a joint Bell-basis measurement on qubits B and C to entangle A and D. This demonstrates the core principle of quantum repeaters, enabling long-distance entanglement through short hops.
