AI-powered quantum circuit compression accelerating quantum computing
QMill Circuit Compression provides a record-breaking method for compressing quantum circuits. This AI-powered solution preserves the full functionality of the circuit. It is available as a service hosted by QMill and as a private deployment.
Compressed circuits have typically 20-50% reduction in gate count and circuit depth enabling
- Improved performance with faster runtimes
- Improved fidelity and reduced error propagation
- Shorter compute time or less shots meaning lower cloud usage cost
Easy-to-use service reduces work-time in optimizing circuits and powers the quantum community to explore and innovate more. API and SDK are available for easy integration to your workflow.
