Summary
The paper compares the performance of various quantum computing simulators using the Quantum Volume benchmark. The results show that GPU-accelerated simulators outperform CPU-based simulators, with Qiskit-GPU being the fastest for small circuits and Qulacs-GPU being the fastest for larger circuits.
Highlights
- Quantum Volume is a widely adopted benchmark for comparing quantum computing systems.
- GPU-accelerated simulators outperform CPU-based simulators in terms of execution time.
- Qiskit-GPU is the fastest simulator for small circuits, while Qulacs-GPU is the fastest for larger circuits.
- Intel Quantum SDK and Qrack are the only simulators that can handle 33 qubits on a single node.
- Qsim is the fastest CPU-based simulator for large circuits.
- Qibo's multi-threaded CPU execution times are mediocre for small circuits but show good scalability for larger circuits.
- Cirq is the worst-performing framework for low qubit counts but surpasses Qulacs CPU for high qubit counts.
