Detailed Description

Entanglement swapping via a quantum repeater (source-centric BSG model).

Two dedicated Bell-State Generator (BSG) source nodes create the link-level entanglement and distribute the qubits: Src1 generates (fly_a, rep_a): fly_a -> Alice, rep_a -> Repeater. Src2 generates (rep_b, fly_b): rep_b -> Repeater, fly_b -> Bob.

Once Alice and Bob receive their flying qubits they each send a classical ACK to the Repeater. When both ACKs arrive the Repeater performs a Bell-State Measurement (BSM) on mem_a and mem_b, swapping entanglement end-to-end. BSM outcomes are forwarded to Bob, who applies the Pauli corrections.

Timing model (illustrative): kSingleGate = 100 ns (single-qubit gate) kTwoQGate = 300 ns (two-qubit gate / BSM) kQDelay = 10 ns (quantum channel propagation, ~2 m fiber)

Visualization output is written to examples/example_traces/q2nsviz-repeater-swap-example.json and can be loaded in the q2nsviz viewer (src/q2ns/utils/q2nsviz-serve.sh).
