Abstract: The universal transpose of quantum states is an anti-unitary transformationthat is not allowed in quantum theory. In this work, we investigateapproximating the universal transpose of quantum states of two-level systemsqubits using the method known as the structural physical approximation topositive maps. We also report its experimental implementation in linear optics.The scheme is optimal in that the maximal fidelity is attained and alsopractical as measurement and preparation of quantum states that areexperimentally feasible within current technologies are solely applied.
