  "abstract": "We propose an expansion of the unitary evolution operator, associated to a given Schr\\\"odinger equation, in terms of a finite product of explicit unitary operators. In this manner, this unitary expansion can be truncated at the desired level of approximation, as shown in the given examples.",
