And a blind two-qubit gate across two remote network nodes (two labs located on different floors of our building) again servers don't know whether the gate is entangling or not - this information is only available to the client who only possesses a photon detector and an AOM.

Also, a two-qubit blind gate inside one node of our network which hides whether the gate is entangling or identity, controlled by the client (unknown to the server).

We performed universal single-qubit gates blindly, including Identity 🤣, Hadamart and a non-Clifford gate. arxiv.org/abs/2412.03020

Our paper on distributed blind computing is out on Arxiv! In short: we performed gates on our spin qubits remotely using photons without our nodes knowing what we did - all thanks to distributed matter-light entanglement 🥳
