qp.labs.estimator_beta.Allocate

class Allocate(num_wires, state=AllocateState.ZERO, restored=False)

Bases: object

A class used to represent the allocation of auxiliary wires to be used in the resource decomposition of a ResourceOperator.

Parameters:

• num_wires (int) – the number of wires to be allocated

• state (Literal["any", "zero"] | AllocateState) – The quantum state of the wires to be allocated, valid values include “zero” or “any”.

• restored (bool) – A guarantee that the allocated register will be restored (deallocated) to its initial state. If True, this requirement will be enforced programmatically.

Raises:

• ValueError – num_wires must be a positive integer

• ValueError – if restored is not a boolean

Example

>>> import pennylane.labs.estimator_beta as qre
>>> qre.Allocate(4)
Allocate(4, state=zero, restored=False)
>>> qre.Allocate(2, state="any", restored=True)
Allocate(2, state=any, restored=True)

Attributes

num_wires	The number of wires to be allocated.
restored	A guarantee that the allocated register will be restored (deallocated) to its initial state.
state	The quantum state of the wires to be allocated, valid values include "zero" or "any".

num_wires
