Query: Realization of a deterministic quantum Toffoli gate with a single photon   Quantum controlled-logic gates, including controlled NOT gate and Toffoli
gate, play critical roles in lots of quantum information processing schemes. We
design and experimentally demonstrate deterministic Toffoli gate by utilizing
orbital-angular-momentum and polarization degrees of freedom of a single
photon. In addition, we generate Bell states by using the controlled NOT gate.
The effective conversion rate of the Toffoli gate in our experiment is
$(95.1\pm3.2)\%$. Furthermore, our experimental setup does not require any
auxiliary photons and probabilistic post selections.
