Qudit-Basis Universal Quantum Computation Using X[superscript (2)]

We prove that universal quantum computation can be realized—using only linear optics and χ[superscript (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...
