Attiva il client Amazon Braket Boto3

Per utilizzare Boto3 con Amazon Braket, devi importare Boto3 e quindi definire un client da utilizzare per connetterti ad Amazon Braket API. Nell'esempio seguente, viene denominato il client Boto3. braket

import boto3
import botocore

braket = boto3.client("braket", config=botocore.client.Config(user_agent_extra="BraketSchemas/1.8.0"))

Ora che hai stabilito un braket cliente, puoi effettuare richieste ed elaborare le risposte dal Amazon Servizio Braket. Puoi ottenere maggiori dettagli sui dati di richiesta e risposta nel APIReference.

Cerca dispositivi

• search_devices(**kwargs)

Cerca dispositivi utilizzando i filtri specificati.

# Pass search filters and optional parameters when sending the
#  request and capture the response
response = braket.search_devices(filters=[{
    'name': 'deviceArn',
    'values': ['arn:aws:braket:::device/quantum-simulator/amazon/sv1']
}], maxResults=10)

print(f"Found {len(response['devices'])} devices")

for i in range(len(response['devices'])):
    device = response['devices'][i]
    print(device['deviceArn'])

Recupera un dispositivo

• get_device(deviceArn)

Recupera i dispositivi disponibili in Amazon Braket.

# Pass the device ARN when sending the request and capture the repsonse
response = braket.get_device(deviceArn='arn:aws:braket:::device/quantum-simulator/amazon/sv1')

print(f"Device {response['deviceName']} is {response['deviceStatus']}")

Crea un'attività quantistica

• create_quantum_task(**kwargs)

Crea un'attività quantistica.

Recupera un compito quantistico

• get_quantum_task(quantumTaskArn)

Recupera il task quantistico specificato.

# Pass the quantum task ARN when sending the request and capture the response

Cerca attività quantistiche

• search_quantum_tasks(**kwargs)

Cerca attività quantistiche che corrispondono ai valori di filtro specificati.

# Pass search filters and optional parameters when sending the
#  request and capture the response

    print(f"Quantum task {task['quantumTaskArn']} for {task['deviceArn']} is {task['status']}")

Annulla attività quantistica

• cancel_quantum_task(quantumTaskArn)

Annulla l'attività quantistica specificata.

# Pass the quantum task ARN when sending the request and capture the response
response = braket.cancel_quantum_task(quantumTaskArn='arn:aws:braket:us-west-1:123456789012:quantum-task/ce78c429-cef5-45f2-88da-123456789012')
