Detailed Description

GHZ state generation and distribution across 4 nodes.

Node1 locally prepares a 4-qubit GHZ state:

|GHZ> = (|0000> + |1111>) / sqrt(2)

using a Hadamard gate on q0 followed by three sequential CNOT(q0, qi) for i in {1,2,3} (serialized because all share q0 as control). It then keeps q0 and distributes q1->Node2, q2->Node3, q3->Node4 over quantum links, completing the shared entangled resource.

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

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