# qiskit.synthesis.synth\_stabilizer\_depth\_lnn
<Function id="qiskit.synthesis.synth_stabilizer_depth_lnn" isDedicatedPage={true} github="https://github.com/qiskit/qiskit/tree/stable/0.24/qiskit/synthesis/stabilizer/stabilizer_decompose.py" signature="synth_stabilizer_depth_lnn(stab)">
Synthesis of an n-qubit stabilizer state for linear-nearest neighbour connectivity, in 2-qubit depth 2\*n+2 and two distinct CX layers, using CX and phase gates (S, Sdg or Z).
**Parameters**
**stab** ([*StabilizerState*](qiskit.quantum_info.StabilizerState "qiskit.quantum_info.StabilizerState")) a stabilizer state.
**Returns**
a circuit implementation of the stabilizer state.
**Return type**
[QuantumCircuit](qiskit.circuit.QuantumCircuit "qiskit.circuit.QuantumCircuit")
