IonQ cost estimation

Overview

When submitting jobs to IonQ devices on QuREKA, acredits costare estimationcalculated based on gate count after circuit compilation and deducted immediately at the time of job submission. No manual confirmation step is requiredrequired.

Credit Calculation

IonQ billing is calculated based on 1Q and 2Q gate counts in the jobcompiled cancircuit be submitted. This allows you to reviewand the expectednumber creditof usageshots.

Formula

Estimated Credit = (1Q Gate unit price × 1Q Gate count + 2Q Gate unit price × 2Q Gate count) × Shots

The minimum floor applies when the calculated amount falls below the threshold.

How It Works

1. Cost Estimation Request

Before submitting a job, QuREKA automatically initiatesperforms a cost estimation.estimation based on gate count after circuit compilation. No credits are deducted at this stage.

2. ReviewAutomatic EstimationDeduction Resultsand Execution

Once the estimation is complete, you can review the expected credit amount in Quantum Jobs. Estimation results are valid for 12 hours from the time of completion. Your job must be submitted within this window.

3. Job Submission and Credit Deduction

After reviewing the estimated cost, confirm and submit your job. Creditscredits are deducted atimmediately and the pointjob ofis submission.submitted for execution. No manual confirmation step is required.

Once the job is complete, you can check the execution results in Quantum Jobs. A full record of credit deductions is available in your credit history.

Debiasing (Error Mitigation)

Debiasing is an optional error mitigation feature provided by IonQ that can be applied at the time of job submission.IonQ.
