With Amazon Braket, you can get started exploring quantum computing with the AWS Free Tier and the open-source Amazon Braket software development kit (SDK). Learn more about the AWS Free Tier with Amazon Braket below.

Beyond the AWS Free Tier, there are no upfront charges, and you only pay for the AWS resources you use. Amazon Braket provides access to quantum computers, managed quantum circuit simulators, and managed Jupyter notebook development environments. You will be billed separately for use of each of these capabilities, as well as other AWS services that you use with Amazon Braket such as Amazon S3 for storing the results of quantum computations.

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

  • Quantum Computers
  • There are two pricing components when using a quantum computer, or quantum processing unit (QPU), on Amazon Braket: 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 or Rigetti. When you use a D-Wave quantum annealer, a shot is when you obtain a result sample of a quantum annealing problem. The per-shot pricing depends on the type of 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 Amazon Braket. Per-task pricing is the same across all QPUs.

  • Simulators
  • With Amazon Braket, you have a choice of four quantum circuit simulators to run and test quantum algorithms, including the local simulator in the Amazon Braket SDK, and three fully managed simulators: SV1, DM1, and TN1. SV1 is a general purpose quantum circuit simulator, and DM1 enables you to simulate the effect of noise on your circuits, whereas TN1 specializes in larger scale simulations for certain types of quantum circuits. All fully managed simulators automatically scale AWS computing resources to deliver high-performance execution of your quantum algorithms.

    The cost of using the Amazon Braket managed simulators is based on the duration of each simulation task. You are billed at a per-minute rate, in increments of one millisecond, for the time your simulation takes to execute. When you use managed simulators, you are billed for a minimum of 3 seconds per simulation.

    The local simulator in the Amazon Braket SDK is provided at no cost, and can run on your laptop, or within an Amazon Braket managed notebook. The local simulator is well suited for running small and medium-scale simulations up to 25 qubits without noise or up to 12 qubits with noise, depending on your hardware. You can use the local simulator for rapid prototyping, debugging or testing, before running your circuit on high-performance managed simulators and quantum computers.

    The Amazon Braket SV1 simulator is a fully managed state vector simulator for quantum circuits. A state vector simulator takes the full wave function of the quantum state and applies the operations of the circuit to calculate the result. You can use SV1 after you have designed your quantum algorithm in the Amazon Braket SDK with the local simulator, and then test your algorithm at scale using the parallel processing of SV1 to run batches of simulations. SV1 supports simulations up to 34 qubits.

    The Amazon Braket DM1 simulator is a fully managed simulator that uses density matrix calculations to simulate the effects of noise on quantum circuits. With DM1, you can specify realistic error models for your circuits and study the impact of noise on your algorithms. DM1 supports the simulation of circuits up to 17 qubits.

    The Amazon Braket TN1 simulator is a fully managed tensor network simulator used for structured quantum circuits. A tensor network simulator encodes quantum circuits into a structured graph to find the best way to compute the outcome of the circuit. You can use TN1 to simulate certain types of quantum circuits up to 50 qubits in size. 

  • Managed Notebooks
  • Amazon Braket provides fully managed Jupyter notebooks so you can build your quantum algorithms, share code, test your algorithm, and visualize your results. When you create a notebook in Amazon Braket, it will be hosted and billed by Amazon SageMaker, the AWS machine learning service. With Amazon Braket managed notebooks, you can choose your preferred instance type to run each notebook and you will be billed per hour for usage, according to pricing for the selected instance type. For usage under one hour, cost is prorated based on the hourly price. The cost of using each notebook will be listed in the Amazon SageMaker portion of your bill.

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

AWS Free Tier

Amazon Braket is part of AWS Free Tier. AWS Free Tier gives you one free hour of quantum circuit simulation time per month during the first 12 months of use. This applies to simulation time on SV1, DM1, TN1, or any combination of the three managed quantum circuit simulators. Standard rates for incremental usage apply after the free hour has been used.

Pricing Examples

Example 1: Managed simulator

Let’s say a developer designs a quantum circuit to use 30 qubits and simulates the circuit using the Amazon Braket managed simulator SV1 ($0.075 per minute) in the AWS US East (N. Virginia) region. The simulation takes 4 minutes to execute. The developer is running this simulation after using Amazon Braket for 10 months, with no other simulation usage so far that month.

This workload is covered by the AWS Free Tier, which provides one hour of included managed simulation time per month for the first twelve months of using Amazon Braket.
Total charges for first 12 months: $0.

If the developer runs the same simulation after using Amazon Braket for twelve months, standard SV1 pricing ($0.075 per minute) applies:
($0.075 / minute) x 4 minutes =$0.30
Total charges after first 12 months: $0.30

Example 2: Quantum annealer

A researcher runs a quantum annealing problem on the D-Wave Advantage quantum computer in the AWS US West (Oregon) Region. This task includes 2,000 result samples of the same annealing problem. The cost to execute this task includes a per-task charge of $0.30, plus 2,000 shots at a per-shot price of $0.00019.

Total charges:
Task charges: 1 task x ($0.30 / task) = $0.30
Shots charges: 2,000 shots x ($0.00019 / shot) = $0.38
Total: $0.68

Example 3: Gate-based QPU

A scientist runs a quantum algorithm on the Rigetti Aspen-9 quantum computer in the AWS US West (N. California) Region. This task includes 10,000 repeated shots of the same circuit design. The cost to execute this task includes a per-task charge of $0.30, plus 10,000 shots at a per-shot price of $0.00035.

Total charges:
Task charges: 1 task x $0.30 / task = $0.30
Shots charges: 10,000 shots x $0.00035 / shot = $3.50
Total: $3.80
