How credits work

Credits are your account balance for running on real quantum hardware. What is free, where your balance lives, and how to earn more.

Credits are a balance on your account. You spend them to run on real quantum hardware, and nothing else on Qollab costs credits.

What is free

Every simulator is free, both the ones that run locally in your browser and the ones that run remotely on IonQ's cloud. You can write, run, and publish an entire project without spending a credit. Compute backends shows which backends are simulators and which are hardware.

Your balance

Your credit balance lives in your profile settings, where you can also set a spending limit so a hardware run never goes over your budget. When a run would cost more than your balance, the runner tells you and links you to where to get more.

Getting credits

The way to earn credits today is the Qollab Grant Program: port, fork, or publish open-source quantum work on Qollab, and get compute credits for it. The award amounts, and how those credits are issued and expire, live on the program page and its terms.
