With Amazon Braket, there are no upfront charges, and you only pay for the AWS resources you use. You will be billed separately for each Amazon Braket capability, including access to quantum computing hardware and managed simulators. You will also be billed separately for AWS services provided through Amazon Braket such as Amazon Braket managed notebooks.

If you need expert help as you explore quantum computing, our Amazon Quantum Solutions Lab professional services team and our quantum computing technology and consulting partners can help. You can request information about an engagement with them here.

Managed Notebook

When you create a notebook in Amazon Braket, it will be hosted and billed by Amazon SageMaker. You choose your preferred instance type to run each notebook and you will be billed per hour for your usage, according to the pricing for the selected instance type. For usage under one hour, the cost is prorated based on the hourly pricing. The cost of using each notebook will be listed on your SageMaker bill.

For details on the pricing of different notebook instance types, refer to the Amazon SageMaker pricing page. Select the relevant region, open the “Building” section, and select the On-Demand ML Notebook Instance type that you plan to use.

Simulators

You have a choice of how to run simulations of gate-based quantum algorithms. You can run simulations locally on your own hardware, run them within your managed notebook on your chosen instance type, or you can use the fully managed simulation capability provided by Amazon Braket. The local simulator is provided for free as part of the Amazon Braket SDK and is suitable for running small and medium scale simulations (typically up to 25 qubits). For larger, more complex algorithms (up to 34 qubits) that require high-performance compute resources, you can submit simulation tasks to the Amazon Braket service. The cost of using the Amazon Braket simulator is based on the duration of each simulation task. You will be billed at an hourly rate, in increments of one second, for the time taken to execute your simulation. If you use the managed simulator, you will be billed for a minimum of 15 seconds.

The Amazon Braket simulator is billed at a rate of $4.50 per hour.

Quantum Computers

There are two pricing components when using a quantum processing unit (QPU) on Amazon Braket. You will be charged both a per-task and a per-shot fee.

A shot is a single execution of a quantum algorithm, such as a single pass through each stage of a complete quantum circuit on a gate-based quantum computer, or one result sample of quantum annealing problem. The per-shot pricing depends on the QPU used. The per-shot price is not affected by the number or type of gates used in a quantum circuit or the number of variables used in a quantum annealing problem.

A task is a sequence of repeated shots based on the same circuit design or annealing problem. You define how many shots you want included in a task when you submit the task to the Amazon Braket service. Per-task pricing is the same across all types of quantum computer.

Pricing for each hardware provider and type of quantum computer is listed in the table below:

Pricing Examples

Example #1 – Managed simulator

A developer designed a quantum circuit to use 30 qubits and simulated the circuit using the Amazon Braket managed simulator. The simulation took 69 minutes (1.15 hours) to execute. The developer was charged at a rate of $4.50 per hour, for a total of $5.175.

Example #2 – Quantum annealer

A researcher ran a quantum annealing problem on the D-Wave 2000Q quantum computer. This task included 2,000 result samples of the same annealing problem. The cost of executing this task was $0.68 (a per-task charge of $0.30, plus 2000 shots at a per-shot price of $0.00019).

Example #3 – Gate-based QPU

A scientist ran a quantum algorithm on the Rigetti Aspen-8 quantum computer. This task included 10,000 repeated shots of the same circuit design. The cost of executing this task was $3.80 (a per-task charge of $0.30, plus 10,000 shots at a per-shot price of $0.00035).
