PauliSum

Base class: Object

Object that represents a sum of Pauli strings.

Represents a sum of Pauli strings and a complex coefficients stored as PauliTerms.

Constructors

PauliSum() -> PauliSum

Constructs an empty PauliSum.

PauliSum(const PauliTerm term) -> PauliSum

Constructs a PauliSumMap from a single PauliTerm.

Parameters

• term: The PauliTerm to construct the PauliSum from.

Members

Name	Description
append	Appends a PauliTerm to the PauliSum.
commutator	Calculates the commutator [S,T] of the PauliSum S with a PauliSum T.
multiplied	Multiplies the PauliSum by a complex scalar out of place.
multiply	Multiplies the PauliSum by an integer scalar in place.
pauli_rotate	Rotates the PauliSum by an angle about an axis specified by a PauliTerm in place.
pauli_rotated	Rotates the PauliSum by an angle about an axis specified by a PauliTerm out of place.
prune	Prunes the PauliSum by removing terms with a coefficient magnitude less than tol and a weight greater than max_weight.
size	Returns the number of PauliTerms in the PauliSum.
