Detailed Description

Distributed graph state generation across an orchestrator and three clients.

An orchestrator locally builds a 5-qubit linear cluster state (graph state): q0 - q1 - q2 - q3 - q4 It then distributes the even-indexed qubits (q0, q2, q4) to three clients and measures the odd-indexed qubits (q1, q3) in the X-basis, effectively transmitting entanglement onto the clients via single-qubit measurements.

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

CZ gate scheduling uses two non-overlapping layers: Layer 1 (non-overlapping): CZ(q0,q1), CZ(q2,q3) Layer 2 (non-overlapping): CZ(q1,q2), CZ(q3,q4) The 5 Hadamards (independent qubits) can be applied in parallel.

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

See docs/tutorials/tutorial-01.md for a detailed walkthrough.
