quara.objects.operators module

compose_qoperations(*elements)

calculates composition of qoperations.

this function can calculate composition of the following combinations of types:

• (Gate, Gate) -> Gate

• (Gate, MProcess) -> MProcess

• (MProcess, Gate) -> MProcess

• (MProcess, MProcess) -> MProcess

• (Gate, State) -> State

• (Gate, StateEnsemble) -> StateEnsemble

• (MProcess, State) -> State or StateEnsemble

• (Mprocess, StateEnsemble) -> StateEnsemble

• (Povm, Gate) -> Povm

• (Povm, MProcess) -> Povm

• (Povm, State) -> MultinomialDistribution

• (Povm, StateEnsemble) -> List[MultinomialDistribution]

• list conststs of these combinations

Returns

composition of qoperations.

Return type

Union[Gate, Povm, State, List[float], MProcess, StateEnsemble, MultinomialDistribution]

Raises

TypeError – Unsupported type combination.

tensor_product(*elements)

calculates tensor product of elements.

this function can calculate tensor product of the following combinations of types:

• (Gate, Gate) -> Gate

• (Gate, MProcess) -> MProcess

• (MProcess, Gate) -> MProcess

• (MProcess, MProcess) -> MProcess

• (MatrixBasis, MatrixBasis) -> MatrixBasis

• (State, State) -> State

• (State, StateEnsemble) -> StateEnsemble

• (StateEnsemble, State) -> StateEnsemble

• (StateEnsemble, StateEnsemble) -> StateEnsemble

• (Povm, Povm) -> Povm

• list conststs of these combinations

Returns

tensor product of elements

Return type

Union[MatrixBasis, State, Povm, Gate]

Raises

TypeError – Unsupported type combination.
