cirq.PauliSumExponential
Represents an operator defined by the exponential of a PauliSum.
cirq.PauliSumExponential(
pauli_sum_like: 'cirq.PauliSumLike',
exponent: Union[int, float, sympy.Expr] = 1,
atol: float = 1e-08
)
Used in the notebooks
Given a hermitian/anti-hermitian PauliSum PS_1 + PS_2 + ... + PS_N, this
class returns an operation which is equivalent to
exp(j * exponent * (PS_1 + PS_2 + ... + PS_N)).
This class only supports commuting Pauli terms.
