Build real quantum skills.
Prove them.
For STEM students and transitioning engineers who want hands-on quantum programming — not lectures and certificates.
Challenge Engine
Progressive quantum programming challenges with real constraints. Every challenge specifies target outcomes, gate limits, and evaluation criteria. Your solution is executed and scored — not self-assessed.
Categories span fundamentals through advanced algorithms. Novice, Journeyman, and Master difficulty levels with progressively tighter constraints.
Hello Quantum
Apply an X gate to produce the |1⟩ state.
from qiskit import QuantumCircuit qc = QuantumCircuit(2, 2) qc.h(0) qc.cx(0, 1) qc.measure([0, 1], [0, 1])
Coding Sandbox
Write and execute quantum circuits directly in the browser. No SDK installation. No credential management. Your code runs against a statevector simulator and is scored instantly.
Real-time feedback on correctness and gate efficiency. Build, iterate, and improve — the way real engineering works.
Performance Profile
Every challenge you solve adds to a persistent, verifiable record of your quantum programming ability. Medals, rankings, and efficiency scores that you can share.
Your profile becomes objective evidence for employers and institutions. Not a certificate — a track record.
