On-Demand Pricing

Credits

Access to both classical and quantum computing resources is managed through the qBraid credits system, which operates on a pay-as-you-go basis. Each qBraid credit is worth $0.01 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 a promo code. You can check your current credit balance on your account page, under the “Profile” drop-down in the top right of qBraid Lab, or using the qBraid-CLI. Prices for both classical and quantum computing resources are subject to change.

Quantum Computers

There are three pricing components for on-demand use of a quantum computer, or quantum processing unit (QPU), on qBraid: a per-minute fee, per-task fee, and per-shot 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, IQM, or AQT, 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 it.

Pricing Structure

• Per-minute pricing: Applies to specific QPUs (e.g., Pasqal Fresnel) where execution time is billed
• Per-task pricing: Consistent across most QPUs (typically 30 credits)
• Per-shot pricing: Varies by QPU type (<1 to 8 credits for current offerings)

For gate-based QPUs, neither per-shot nor per-minute prices are affected by the number or type of gates used. Note that error mitigation on IonQ’s Aria QPU requires a minimum of 2,500 shots per task.

Pasqal	Fresnel	500 credits	0 credits	0 credits

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.

qBraid offers twelve on-demand quantum circuit simulators for testing quantum algorithms:

• qBraid QIR Simulator: employs sparse state vector simulation based on arXiv:2105.01533.
• AWS State Vector 1 (SV1): serves as a general purpose quantum circuit simulator.
• AWS Density Matrix 1 (DM1): enables simulating the effect of noise on your circuits.
• AWS Tensor Network 1 (TN1): specializes in simulation of larger scale quantum systems.
• Rigetti QVM Simulator: Quantum Virtual Machine (QVM) open-source simulator.
• IonQ Simulator: supports “ideal” simulations as well as noise models for harmony (legacy), aria-1, aria-2, forte-1, and forte-enterprise-1.
• NEC Vector Annealer: executes proprietary algorithm for annealing processing on NEC’s vector supercomputer “SX-Aurora TSUBASA“
• Quantinuum H2-1 Syntax Checker: Validates quantum programs against the H2-1 compiler.
• Quantinuum H2-1 Emulator: Emulation tool containing a realistic noise model of the actual System Model H2 hardware.
• Pasqal Emulator: Neutral atom tensor network emulator. Runs on a cluster of DGX nodes with NVIDIA A100 GPUs.
• Equal1 Bell-1 Simulator: State-vector simulator supporting Equal1 Bell-1 QPU noise models; GPU acceleration available
• Quobly Alloy Forge Emulator: Emulator of the Quobly Alloy Pioneer 10 qubit QPU.

All simulators automatically scale resources to ensure high-performance. Billing is based on a fixed per-task cost plus the duration of each simulation, charged per minute in one-millisecond increments, with a minimum billing duration of three seconds per simulation.

CPUs and GPUs

qBraid Lab offers two ways to access compute: subscription instances billed against your monthly CPU hours, and on-demand instances billed per minute in credits.

Subscription Instances

Your subscription plan includes a monthly allocation of CPU hours. The following CPU instances draw from that quota:

Instance	vCPU	RAM	Credits/Min (Overdraft)
Small	2	4GB	0.20
Medium	4	12GB	0.40
Large	8	25GB	0.80

If you exceed your monthly CPU hours, you can auto-switch to credits — usage then bills at the per-minute credit rates shown above. These rates are consistent with on-demand pricing, so there is no difference in cost between overdraft and on-demand for the same compute. See usage limits for more details on compute hour tracking.

On-Demand Instances

On-demand instances are billed per minute in credits, with no subscription commitment required. This includes all GPU instances and additional high-spec CPU configurations. See On-Demand Instances for the full lifecycle guide.

Subscription discounts on on-demand pricing:

Plan	Discount
Free	—
Standard	10% off
Pro	18% off

Standard and Pro subscribers receive an automatic discount on all on-demand instances (GPUs and on-demand CPUs). The discount is applied at billing time — the effective rate is shown on your dashboard alongside the list price.

The Slug column is the profile identifier used with the qBraid CLI. For example:

$ qbraid compute up gpu-h100-sxm
