Working with reservations
Reservations give you exclusive access to the quantum device of your choice. You can schedule a reservation at your convenience, so you know exactly when your workload starts and ends execution. Reservations are available in 1-hour increments for all Braket devices and can be cancelled up to 48 hours in advance, at no additional charge. We recommend queuing quantum tasks and hybrid jobs for an upcoming reservation in advance, using your Braket Direct Reservation ARN, or submitting workloads during your reservation.
The cost of dedicated device access is based on the duration of your reservation,
regardless of how many quantum tasks and hybrid jobs you run on the quantum processing unit
(QPU). An updated list of quantum computers available for reservations can be found on our pricing page
Note
In a reservation, there are no gateshot limits. Additionally, for IonQ devices, the minimum shot count for Error mitigation tasks is reduced to 500 (vs. 2500 for on-demand).
When to use a reservation
Leveraging reservation access provides you the convenience and predictability of knowing exactly when your quantum workload starts and ends execution. Compared to submitting tasks and hybrid jobs on-demand, you do not have wait in a queue with other customer tasks. Because you have exclusive access to the device during your reservation, only your workloads run on the device for the entirety of the reservation.
We recommend using on-demand access for the design and prototyping phase of your research, enabling quick and cost-efficient iteration of your algorithms. Once you are ready to produce final experiment results, consider scheduling a device reservation at your convenience to ensure that you can meet project or publication deadlines. We also recommend using reservations when you desire task execution during specific times, such as when you're running a live demo or workshop on a quantum computer.
