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. The service helps quantum researchers and developers to work with more complex quantum circuits on current quantum computers and execute faster.
AI-powered quantum circuit compression accelerating quantum computing
QMill™ Circuit Compression was launched as a record-breaking method for compressing quantum circuits. Our recently updated compression algorithm now delivers even better results and supports an expanded range of gate sets. 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.
Do you want to focus on reducing the number of 2-qubit gates, circuit depth or the total number of gates? Compression will provide
- Improved performance with faster runtimes
- Improved fidelity and reduced error propagation
- Shorter compute time or less shots meaning lower cloud usage cost
Our 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.
