| # Topology (entangling-layer patterns) | |
| Named entangling-layer connectivity patterns for variational circuits (`linear`, `circular`, | |
| `full`, `star`, `brick`) -- the same role Qiskit's `TwoLocal(entanglement=...)` or PennyLane's | |
| `qml.broadcast(pattern=...)` play, returning a plain gate-tuple list ready for `run_circuit`. | |

| **See also**: [`ghz_state`](states.md) builds its CX chain with `entangling_layer(pattern='linear')` | |
| directly. This package's `DenseSVSimulator` has no notion of hardware connectivity at all (any | |
| two qubits can always interact) -- these patterns are an ansatz-design convenience, not a | |
| constraint the simulator enforces. | |
