Running hybrid jobs during a reservation

Once you have a Python function to run as a hybrid job, you can run the hybrid job in a reservation by passing the reservation_arn keyword argument. All tasks within the hybrid job use the reservation ARN. Importantly, the hybrid job with reservation_arn only spins up the classical compute once your reservation starts.

Note

A hybrid job running during a reservation only successfully runs quantum tasks on the reserved device. Attempting to use a different on-demand Braket device will result in an error. If you need to run tasks on both an on-demand simulator and the reserved device within the same hybrid job, use DirectReservation instead.

The following code to runs a hybrid job during a reservation.

from braket.aws import AwsDevice
from braket.devices import Devices
from braket.jobs import get_job_device_arn, hybrid_job

@hybrid_job(device=Devices.IonQ.Aria1, reservation_arn="<my_reservation_arn>")
def example_hybrid_job():
    # declare AwsDevice within the hybrid job
    device = AwsDevice(get_job_device_arn())
    bell = Circuit().h(0).cnot(0, 1)
    
    task = device.run(bell, shots=10)

For hybrid jobs that use a Python script (see Create your first Hybrid Job), you can run them in the reservation by passing the reservation_arn keyword argument

from braket.aws import AwsQuantumJob 
from braket.devices import Devices

job = AwsQuantumJob.create( 
    Devices.IonQ.Aria1, 
    source_module="algorithm_script.py", 
    entry_point="algorithm_script:start_here",
    reservation_arn="<my_reservation_arn>"
)
