Experimental Evaluation of Adder Circuits on IBM QX Hardware

This work experimentally evaluated the performance of quantum adders on various IBM quantum hardware. The authors have constructed quantum circuits for one-qubit and two-qubit quantum adders using Quantum Information Science Kit (Qiskit) and run the circuit on seven IBM quantum devices: YorkTown, Ourense, Valencia, Santiago, Athens, Vigo and Melbourne. Adetailed experimental analysis of accuracy rate of seven IBM devices are reported in this work. Experimental analysis shows that IBM Athens (5 qubits) provides the best accuracy results (73.7%) in comparison to high-qubit IBM Melbourne (15 qubits) for one-qubit quantum adder. Experimental analysis shows that IBM Melbourne (15 qubits), the only real IBM quantum hardware presently available with qubits higher than 5 qubits, provides an accuracy of 12.8125% over the ideal simulator.

Automated summary
