Description:
Author(s): Murphy Yuezhen Niu, Isaac L. Chuang, and Jeffrey H. Shapiro We prove that universal quantum computation can be realized—using only linear optics and χ ( 2 ) (three-wave mixing) interactions—in any ( n + 1 )-dimensional qudit basis of the n -pump-photon subspace. First, we exhibit a strictly universal gate set for the qubit basis in the one-pump-photon subspace. Next... [Phys. Rev. Lett. 120, 160502] Published Wed Apr 18, 2018
