How has IBM improved the performance of Qiskit for quantum computing?

IBM has significantly improved Qiskit's performance by converting its underlying code from Python to Rust, resulting in a 58x faster transpilation speed compared to the second-best competitor. This transformation not only made Qiskit more efficient at creating quantum circuits with 21% fewer two-qubit gates, but also enhanced its overall functionality. Benchpress, IBM's open-source benchmarking tool, demonstrated that Qiskit outperforms other SDKs in comprehensive testing, passing more of the 1,000+ tests than any alternative. These improvements make Qiskit the optimal choice for quantum workloads requiring speed, quality, and scale.
