Start a free trial
Create one account and verify your email. Then choose Quantum Compiler or Optimizer for QUBO and activate its trial whenever you're ready. The 15-day period starts when you activate that product, not when you register. You can activate the other product later, with its own independent allowance.
No credit card required. API credentials are issued when you activate your chosen trial.
Quantum Compiler
Compile supported circuits, inspect the optimized result and use the API during your trial.
Optimizer for QUBO
Submit QUBO and Ising models, set a search budget and inspect improving results.
What happens after the trial?
Your Explore trial includes 120 solver minutes over 15 days. New runs stop when either limit is reached, but your account and existing results remain available to view. API credentials stay associated with your account; new API computations resume when you subscribe.
If you continue, choose a Developer or Team subscription for that product. Each subscription has its own monthly time allowance and limits. Paid customers can purchase additional solver minutes as needed, with the price shown before purchase.
