Quantum System QRMI - Examples in C#

GitHub

Prerequisites#

Set environment variables#

Because QRMI is an environment variable driven software library, all configuration parameters must be specified in environment variables. The required environment variables are listed below. This example assumes that a .env file is available under the current directory.

Environment variables

Descriptions

{resource_name}_QRMI_IBM_QS_ENDPOINT

Quantum System endpoint URL

{resource_name}_QRMI_IBM_QS_IAM_ENDPOINT

IBM Cloud IAM endpoint URL (e.g. https://iam.cloud.ibm.com)

{resource_name}_QRMI_IBM_QS_IAM_APIKEY

IBM Cloud IAM API Key

{resource_name}_QRMI_IBM_QS_SERVICE_CRN

Cloud Resource Name (CRN) of the provisioned Quantum System instance, starting with crn:v1:.

{resource_name}_QRMI_IBM_QS_AWS_ACCESS_KEY_ID

AWS Access Key ID to access S3 bucket

{resource_name}_QRMI_IBM_QS_AWS_SECRET_ACCESS_KEY

AWS Secret Access Key to access S3 bucket

{resource_name}_QRMI_IBM_QS_S3_ENDPOINT

S3 endpoint URL

{resource_name}_QRMI_IBM_QS_S3_BUCKET

S3 bucket name

{resource_name}_QRMI_IBM_QS_S3_REGION

S3 bucket region name (e.g. us-east)

{resource_name}_QRMI_JOB_TIMEOUT_SECONDS

Time (in seconds) after which job should time out and get cancelled. It is based on system execution time (not wall clock time). System execution time is the amount of time that the system is dedicated to processing your job.

Create Qiskit Primitive input file as input#

Refer to this tool to generate. You can customise quantum circuits by editing the code.

Note

Use the file with name ending _params_only.json, e.g. sampler_input_ibm_torino_params_only.json.

How to build this example#

mkdir build
