T-count Optimized Design of Quantum Integer Multiplication

Understand

Quantum circuits of many qubits are extremely difficult to realize; thus, the number of qubits is an important metric in a quantum circuit design.

• Further, scalable and reliable quantum circuits are based on Clifford + T gates.
• An efficient quantum circuit saves quantum hardware resources by reducing the number of T gates without substantially increasing the number of qubits.
• Recently, the design of a quantum multiplier is presented by Babu [1] which improves the existing works in terms of number of quantum gates, number of qubits, and delay.
