IQM Backend¶

IQM's quantum computers are universal, gate-based machines that utilize superconducting qubits. This superconducting quantum hardware excels in scalability and control, making it a strong contender for fault-tolerant quantum computing and enabling users to achieve the highest quality and accuracy for Noisy-Intermediate-Scale-Quantum applications. IQM's hardware is hosted on Amazon Braket. Find out more about IQM's hardware here.

Using Environment Variables

You can set your AWS credentials via environment variables to avoid passing them during initialization:

export LUNA_AWS_ACCESS_KEY=your_aws_access_key
export LUNA_AWS_SECRET_ACCESS_KEY=your_aws_secret_access_key

Initialization¶

Initialize the IQM backend with:

from luna_quantum.backends import IQM

backend = IQM(
    aws_access_key=None,
    aws_secret_access_key=None,
    aws_session_token=None,
    device='Garnet'
)

API-Reference¶

IQM ¶

Bases: AWSBackendBase

Configuration parameters for IQM quantum backends, accessed via AWS.

Attributes:

Name	Type	Description
`device`	`Literal["Garnet"], default="Garnet"`	The specific IQM quantum device to use for computations. Currently only "Garnet" is available - IQM's superconducting quantum processor with native two-qubit gates and optimized for near-term algorithms.
`aws_access_key`	`str \| QpuToken \| None`	The AWS access key
`aws_secret_access_key`	`str \| QpuToken \| None`	The AWS secret access key
`aws_session_token`	`str \| QpuToken \| None`	The AWS session token

aws_access_key `class-attribute` `instance-attribute` ¶

aws_access_key: str | QpuToken | None = Field(
    repr=False, exclude=True, default=None
)

aws_secret_access_key `class-attribute` `instance-attribute` ¶

aws_secret_access_key: str | QpuToken | None = Field(
    repr=False, exclude=True, default=None
)

aws_session_token `class-attribute` `instance-attribute` ¶

aws_session_token: str | QpuToken | None = Field(
    repr=False, exclude=True, default=None
)

device `class-attribute` `instance-attribute` ¶

device: Literal['Garnet'] = 'Garnet'

provider `property` ¶

provider: str

Retrieve the name of the provider.

Returns:

Type	Description
`str`	The name of the provider.

_get_token ¶

_get_token() -> TokenProvider | None

device_provider ¶

device_provider() -> str

Return the device provider identifier.

get_qpu_tokens ¶

get_qpu_tokens() -> TokenProvider | None

Retrieve a QPU token.

This method is intended to be implemented by subclasses to provide the mechanism for fetching the required Quantum Processing Unit (QPU) tokens, if they are required by the solver implementation. The tokens may either be sourced from a TokenProvider object or result in a None if unavailable.

Returns:

Type	Description
`TokenProvider \| None:`	An object implementing the `TokenProvider` interface if tokens are available/needed, otherwise `None`.
