CirQit is a professional quantum circuit simulator built on NumPy. Six backends, zero heavy dependencies — from 2-qubit Bell states to 1000-qubit stabilizer circuits.
A complete toolkit built from scratch with noise models, variational circuits, error correction, and more.
Six backends covering every quantum computing regime.

CirQit is an open-source Python library for quantum circuit simulation. It provides researchers, students, and developers with a professional-grade toolkit requiring no heavy external dependencies.
The library implements six distinct simulation backends covering every quantum computing regime — from exact statevector simulation to 1000+ qubit Clifford stabilizer circuits. All algorithms are implemented from scratch using NumPy, with no dependencies on commercial quantum computing platforms.

Quantum computing articles, tutorials, and CirQit updates.
CirQit is a free, open-source Python library for professional quantum circuit simulation. We believe quantum computing education should be accessible to everyone — from students learning their first qubit to researchers building fault-tolerant algorithms.
Built entirely on NumPy with zero heavy dependencies, CirQit provides six simulation backends, 20+ quantum gates, noise models, variational circuits, quantum error correction codes, and a full job tracking system — all installable with a single pip install cirqit command.
To make quantum computing simulation accessible, educational, and production-ready for the global developer community. This blog publishes original articles, tutorials, and research insights on quantum computing — all freely available.
