Step 1
Account Setup
Creating an account takes less than a minute. You can sign up using your email address or continue with a social login provider.
To create your account:
- 1Click "Get Started" or "Sign Up" from the landing page.
- 2Enter your email and create a password, or sign in with a social provider.
- 3Choose a display name that will appear on leaderboards and your profile.
- 4Optionally, add your organisation affiliation (university, company, etc.).
- 5You're in. Head to the Challenges page to start solving.
Early Access
During early access, all features are available at $4.99 USD/month with no restrictions. A free tier with introductory challenges will launch with the full release.
Step 3
Your First Challenge
Novice challenges are the best place to start. They use one or two qubits and test fundamental gate operations. Here is the workflow for solving a challenge.
Pick a challenge
Go to the Challenges page and choose a Novice-level challenge. Each card shows the challenge title, difficulty, relevant topics, and your best medal (if any).
Read the instructions
The left panel contains the challenge description, including what your circuit should produce, any constraints (maximum qubits, circuit depth), and medal thresholds. Read carefully before coding.
Write your circuit
The right panel is a code editor preloaded with starter code. Write your Qiskit circuit in the solution() function. The function should return a QuantumCircuit object.
Run or submit
Use Run to test your circuit without it counting as an official attempt. When you are confident, hit Submit to have your solution evaluated. Submissions count toward your score, medals, and XP.
Get your results
After submission, you will see your score, which tests passed or failed, and any medal earned. Results appear in real time as your circuit is executed in an isolated sandbox.
Tip
You can resize the instruction and editor panels by dragging the divider between them. Find the layout that works best for you.
Step 4
Understanding Results
Every submission is evaluated on two dimensions: correctness and efficiency. Understanding the scoring helps you improve faster.
Correctness
Your circuit is executed against a statevector simulator. The platform checks whether your circuit produces the expected output states within a given tolerance.
- Each challenge has one or more test cases
- Tests compare your output probability distribution to the expected result
- Tolerance varies by challenge (typically 5-15%)
- Your score is the percentage of test points passed
Efficiency
Beyond getting the right answer, the platform evaluates how efficiently you solved the problem. Efficient circuits use fewer resources.
- Gate count: total number of gates used
- Circuit depth: longest path through the circuit
- Qubit usage: number of qubits allocated
- Challenges set maximum constraints for each metric
Medal Thresholds
Medals are awarded based on your score and how quickly you submit. Thresholds scale with difficulty:
Gold
95%+ score
Fast completion
Silver
80%+ score
Moderate completion
Bronze
60%+ score
Standard completion
Step 5
Progression & XP
As you solve challenges, you earn experience points (XP) that contribute to your level. XP is awarded for completions, score improvements, and medal achievements.
How XP is Earned
Anti-farming protection
XP is only awarded for genuine improvements. Repeating a challenge without improving your score does not grant additional XP. Practice runs (non-submissions) award no XP.
