QMill Circuit Compression


QMill Circuit Compression is an easy-to-use solution for compressing, running, and comparing quantum circuits. It provides AI-powered quantum circuit compression, accelerating quantum computing and benefiting the entire quantum ecosystem.

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% (up to 70%) 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.
