Frequently Asked Questions
Answers to common questions about the platform, challenges, and pricing.
Getting Started
Do I need quantum computing experience to start?
No prior quantum experience is required. During early access, some programming background and basic linear algebra will help. Guided learning modules are being developed for the full release, which will make the platform accessible with no prior knowledge.
What programming languages are supported?
Challenges use Qiskit (Python-based). You write quantum circuits in a browser-based coding sandbox.
How do I get started?
Create an account, choose a challenge, and start coding. The challenge interface gives you a description, constraints, and a code editor. Submit your circuit and get immediate feedback.
Challenges
How are challenges evaluated?
Your circuit is executed against a statevector simulator. The platform checks correctness (does your circuit produce the expected output?) and scores efficiency (gate count, circuit depth).
What do the medals mean?
Gold, silver, and bronze medals are awarded based on how quickly and efficiently you solve a challenge. Medal thresholds vary by difficulty level.
How long do challenges take?
Novice challenges can take 30 seconds to 5 minutes. Journeyman challenges typically take 5 to 15 minutes. Master-level challenges can take 15 to 30 minutes or more.
Can I see other people’s solutions?
No. Solutions are private. Copy-pasting into the editor is not possible. Your results reflect your own ability.
Platform & Pricing
Is there a free tier?
Not during early access. The current plan is $24.99 USD/month with full platform access. A free tier with introductory challenges will be available with the full release.
What happens after early access?
Pricing will increase and a free tier will be introduced. Early access users help shape the platform’s development.
Can I use this for academic credit?
That’s up to your institution. Your profile provides objective evidence of quantum programming skill that some institutions may accept as supplementary evidence.
