Evaluating Benchmarking Results
IBM’s extensive benchmarking efforts pitted Qiskit against other quantum SDKs, including BQSKit, Braket, Cirq, Staq, and TKET. The benchmarks focused on key metrics such as the speed of transpilation and the efficiency of circuit building. By evaluating these SDKs under stringent conditions, a clear snapshot of their capabilities emerged, revealing significant differences in performance.
Qiskit demonstrated unparalleled performance, successfully completing the majority of the tests and excelling in both speed and the number of two-qubit gates used. Notably, Qiskit was 13 times faster in transpilation and used 24% fewer two-qubit gates compared to TKET. This significant advantage highlights Qiskit’s efficiency and capability in handling complex quantum computations. The rigorous nature of these benchmarks, developed by notable universities and national labs, underpins the reliability of these impressive results.
Role of Circuit Building and Transpilation
Central to the benchmarking process were two primary tasks: circuit building/manipulation and synthesis/transpilation. The ability to create and modify quantum circuits efficiently is crucial for researchers and developers. Equally important is the process of transpilation, converting high-level circuits into hardware-compatible forms. These tasks test both the flexibility and efficiency of the quantum SDK in real-world scenarios.
Qiskit excelled in both areas, showcasing superior speed and reduced gate usage. This dual proficiency sets it apart from other SDKs that often had limitations in either circuit synthesis or transpilation efficiency, impacting their overall performance. By integrating sophisticated algorithms and leveraging advanced technologies, Qiskit ensures that circuits are optimized for execution on quantum hardware, minimizing errors and resource consumption. The thorough approach underscores Qiskit’s readiness for practical applications and extensive research requirements.
