Quantum as a Service API

Introduction

Quantum as a Service (QaaS) allows you access to dedicated sessions to run and monitor jobs on simulated quantum processing units (QPU).

Quickstart

1. Configure your environment variables.

   Note:

   This is an optional step that seeks to simplify your usage of the APIs

   export ACCESS_KEY="<access-key>"
   export SECRET_KEY="<secret-key>"Copy

2. List the available Quantum as a service platforms. A platform is a combination of hardware and software forming a simulated QPU, you can select the one that better fits your use-case from our list.

   curl -X GET \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     -H "Content-Type: application/json" \
     "https://api.scaleway.com/qaas/v1alpha1/platforms"Copy

   You should get a response like the following:

   Important:

   Take note of the UUID of your platform of choice, as it will be used in the next step.

   {
     "total_count": 2,
     "platforms": [
       {
         "id": "282e9874-1761-499d-b0dc-004d0e334837",
         "version": "0.9.2",
         "name": "sim:sampling:p100",
         "provider_name": "quandela",
         "type": "simulator",
         "technology": "photonic",
         "max_qubit_count": 20,
         "metadata": "{\"constraints\": {\"max_photon_count\": 20, \"min_photon_count\": 2}, \"pcvl_version\": \"0.9.2\", \"documentation\": \"\", \"available_commands\": [\"samples\", \"probs\"]}"
       },
       {
         "id": "5e52c364-03fd-4bf7-93e2-e1597e28fb83",
         "version": "0.9.2",
         "name": "sim:sampling:h100",
         "provider_name": "quandela",
         "type": "simulator",
         "technology": "photonic",
         "max_qubit_count": 28,
         "metadata": "{\"constraints\": {\"max_photon_count\": 28, \"min_photon_count\": 2}, \"pcvl_version\": \"0.9.2\", \"documentation\": \"\", \"available_commands\": [\"samples\", \"probs\"]}"
       }
     ]
   }Copy

3. Run the following command to create a session. A session is a time interval where a user can execute quantum jobs on a specific platform.

   curl -X POST \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     -H "Content-Type: application/json" \
     -d '{
       "project_id": "3j336ee9-dff0-4732-8c5a-bc4f2031ddd3",
       "platform_id": "5e52c364-03fd-4bf7-93e2-e1597e28fb83"
     }'\
     "https://api.scaleway.com/qaas/v1alpha1/sessions"Copy

   You can edit the request payload according to the information below:

   Parameter	Description
   project_id	REQUIRED The ID of the Project you want to create your Database Instance in. To find your Project ID you can list the projects or consult the Scaleway console.
   platform_id	ID of your selected platform.

   If the operation was successful you will see a response like the following:

   {
   "id": "6a134dca-5743-4ba6-9999-b84c295d591c",
   "name": "Justina",
   "platform_id": "5e52c364-03fd-4bf7-93e2-e1597e28fb83",
   "started_at": {
       "seconds": "-62135596800",
       "nanos": 0
   },
   "update_at": {
       "seconds": "1700063831",
       "nanos": 389384664
   },
   "max_idle_duration": {
       "seconds": "600",
       "nanos": 0
   },
   "max_duration": {
       "seconds": "1800",
       "nanos": 0
   },
   "waiting_job_count": "0",
   "finished_job_count": "0",
   "status": "starting",
   "project_id": "3j336ee9-dff0-4732-8c5a-bc4f2031ddd3",
   "tags": {
       "value": []
   },
   "deduplication_id": "",
   "created_at": {
       "seconds": "1700063831",
       "nanos": 389384664
   }
   }Copy

   Important:

   Take note of the UUID of your session, as it will be used in the next step.

4. Create a job to execute your quantum cirtuit.

   curl -X POST \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     -H "Content-Type: application/json" \
     -d '{
         "circuit": {
         "perceval_circuit": ":PCVL:zip:eJyzCnAO87FydM4sSi7NLLFydfTM9K9wdI7MSg52DsyO9AkNCtWu9DANqMj3cg50hAPP9GwvBM+xEKgWwXPxRFELAAdTHXM="
         },
         "name": "my_job",
         "session_id": "3j336ee9-dff0-4732-8c5a-bc4f2031ddd3"
         }'\
     "https://api.scaleway.com/qaas/v1alpha1/jobs"Copy

   You can edit the request payload according to the information below:

   Parameter	Description
   perceval_circuit	Your Perceval circuit
   name	The name of your job.
   session_id	The UUID of the session created in the previous step.

   If the operation was successful you will see a response like the following:

   {
   "id": "f0febf59-14b8-4759-b342-09ab061691a3",
   "name": "Loremipsumconsequatdo",
   "tags": {
       "value": []
   },
   "session_id": "f49a7157-93e9-4125-bd3c-b864bb93f6bc",
   "created_at": {
       "seconds": "1700064966",
       "nanos": 251006133
   },
   "updated_at": {
       "seconds": "1700064966",
       "nanos": 251006133
   },
   "started_at": {
       "seconds": "-62135596800",
       "nanos": 0
   },
   "status": "waiting",
   "progress_message": {
       "value": ""
   },
   "job_duration": {
       "seconds": "0",
       "nanos": 0
   },
   "result_distribution": {
       "value": ""
   }
   }Copy

5. Delete your session once the job is complete. Make sure to specify the session_ID in the endpoint.

   Note:

   This is an optional step, as all sessions have a set timeout of

   curl -X DELETE \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     -H "Content-Type: application/json" \
     "https://api.scaleway.com/qaas/v1alpha1/sessions/$SESSION_ID"Copy

   If the operation was successful you will see a response like the following:

   {}Copy
