Detailed Description

Pairwise Bell-pair distribution across 3 fully-connected nodes.

Three nodes (Node1, Node2, Node3) share quantum and classical links in a full-mesh topology. Bell pairs are distributed sequentially so that every pair of nodes ends up sharing one entangled qubit:

Step 1 - Node1 creates Bell pair 0, keeps half, sends the other to Node2. Step 2 - Node1 creates Bell pair 1, keeps half, sends the other to Node3. Step 3 - Node2 creates Bell pair 2, keeps half, sends the other to Node3.

After the protocol each link (1-2, 1-3, 2-3) carries one shared Bell pair.

Timing model (illustrative): kSingleGate = 100 ns (single-qubit gate) kTwoQGate = 300 ns (two-qubit gate) kQDelay = 100 ns (quantum channel propagation, ~20 m fiber)

Steps start at T = 1, 3, 5 us for clear visualization; final trace at ~20 us.

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

See docs/tutorials/tutorial-00.md for a detailed walkthrough.
