Constraints and limitations of quantum circuits must be considered in synthesis of quantum circuits. In certain quantum technologies only physically adjacent qubits are allowed to interact with each other. Linear nearest neighbor architecture must be used when implementing. It is common to bring the control and target qubits of any quantum gate to adjacent lines by adding SWAP gates, and the circuit function is ensured not be affected. A new method for constructing linear nearest neighbor quantum circuits is proposed based on analysis of quantum bit state in circuit. Results show that the proposed scheme can reduce the quantum cost by approximately 30% on average comparing with the existing schemes for all 40320 three-qubit quantum circuits.
