Methods

__init__(dims: Sequence[int]) → None[source]#

Initialize an OperatorTerm object.

Parameters:

dims – Hilbert space dimensions.

) → None[source]#

Append an elementary or matrix product to an operator term.

Parameters:

  • op_prod – Product of elementary or matrix operators to be appended.

  • modes – Modes acted on by the operator product.

  • duals – Dualities of the operator product.

  • coeff – Coefficient of the operator product.

  • coeff_callback – Forward callback for the coeffient.

  • coeff_grad_callback – Gradient callback for the coefficient.
