qml.devices.experimental.ExecutionConfig

class ExecutionConfig(grad_on_execution=None, use_device_gradient=None, gradient_method=None, gradient_keyword_arguments=None, device_options=None, interface='autograd', derivative_order=1)

Bases: object

A class to configure the execution of a quantum circuit on a device.

See the Attributes section to learn more about the various configurable options.

Attributes

derivative_order	The derivative order to compute while evaluating a gradient
device_options	Various options for the device executing a quantum circuit
grad_on_execution	Whether or not to compute the gradient at the same time as the execution.
gradient_keyword_arguments	Arguments used to control a gradient transform
gradient_method	The method used to compute the gradient of the quantum circuit being executed
interface	The machine learning framework to use
use_device_gradient	Whether or not to compute the gradient on the device.

derivative_order: int = 1

The derivative order to compute while evaluating a gradient

device_options: Optional[dict] = None

Various options for the device executing a quantum circuit

grad_on_execution: Optional[bool] = None

Whether or not to compute the gradient at the same time as the execution.

If None, then the device or execution pipeline can decide which one is most efficient for the situation.

gradient_keyword_arguments: Optional[dict] = None

Arguments used to control a gradient transform

gradient_method: Optional[str] = None

The method used to compute the gradient of the quantum circuit being executed

interface: str = 'autograd'

The machine learning framework to use

use_device_gradient: Optional[bool] = None

Whether or not to compute the gradient on the device.

None indicates to use the device if possible, but to fall back to pennylane behavior if it isn’t.

True indicates a request to either use the device gradient or fail.
