An interactive learning platform for building quantum circuits, running them, and practising quantum algorithms.

Landing page captured for the 2026-09-28 issue.
For
Learners practising quantum circuits and Qiskit
Worth noticing
Challenges accept different circuits when their output distributions match the target within 3%.

Field notes

The workspace describes a circuit with up to six qubits and offers probability, state-vector, Bloch-sphere, and code views. Practice is framed around execution: the page says challenges accept output distributions within 3% of a target, and circuit tasks can have multiple valid solutions. The code editor is editable for a restricted Qiskit subset; other frameworks are described as read-only.
