    "abstract": "We propose an interpretation of quantum separability based on a physical\nprinciple: local time reversal. It immediately leads to a simple\ncharacterization of separable quantum states that reproduces results known to\nhold for binary composite systems and which thereby is complete for low\ndimensions. We then describe a constructive algorithm for finding the canonical\ndecomposition of separable and non separable mixed states of dimensions 2x2 and\n2x3.",
