Backends

The divi.backends module provides interfaces for running quantum circuits on different backends, from local simulators to cloud-based quantum hardware.

All backends implement the CircuitRunner interface, providing a consistent API for circuit execution. This abstraction allows switching between different execution environments without changing quantum program code.

All submit_circuits() methods return an ExecutionResult object, which provides a unified interface for handling both synchronous and asynchronous backend responses.
