Pricing
Each qBraid credit is worth $.01 USD, so a quantum job costing $3.80 would subtract 380 credits from your qBraid balance. Credits can be purchased from your account page, or redeemed using an access key. You can check your current credit balance on your account page,
Quantum Computers (on-demand)
There are two pricing components for on-demand use of a quantum computer, or quantum processing unit (QPU), on qBraid: a per-shot fee and a per-task fee.
A shot is a single execution of a quantum algorithm on a QPU. For example, a shot is a single pass through each stage of a complete quantum circuit on a gate-based QPU from IonQ, Rigetti, or OQC. or the time evolution of a Hamiltonian on a QPU from QuEra. A task is a sequence of repeated shots based on the same circuit design or Hamiltonian. You define how many shots you want included in a task when you submit the task to Amazon Braket.
Per-task pricing is the same across all QPUs. The per-shot pricing depends on the type of QPU used. For gate-based QPUs, the per-shot price is not affected by the number or type of gates used in a quantum circuit. Note that the use of error mitigation on IonQ’s Aria QPU requires a minimum of 2,500 shots per task.

Quantum Circuit Simulators
Verify your circuits using a simulator before you run it on a QPU, so you can fine-tune your circuit without incurring charges for QPU usage. Although the results from running the circuit on a simulator may not be identical to the results from running the circuit on a QPU, you can identify coding errors or configuration issues using a simulator.
