ListOp.log_i¶

ListOp.log_i(massive=False)[source]¶

Return a MatrixOp equivalent to log(H)/-i for this operator H. This function is the effective inverse of exp_i, equivalent to finding the Hermitian Operator which produces self when exponentiated. For proper ListOps, applies log_i to all ops in oplist.

Return type: OperatorBase
