WebA photon-photon quantum gate based on a single atom in an optical resonator Bastian Hacker, Stephan Welte, Gerhard Rempe, and Stephan Rittery Max-Planck-Institut fur Quantenoptik, Hans-Kopfermann-Strasse 1, 85748 Garching, Germany Two photons in free space pass each other undisturbed. This is ideal for the faithful trans- WebApr 29, 2016 · Photons are interesting as carriers of quantum information because they hardly interact with their environment and can easily be transmitted over long distances. A deterministic photon-photon gate could be used as the central building block for universal quantum information processing (QIP) ( 1 ).

WebJun 7, 2024 · Deterministic photon-photon gates enable the controlled generation of entanglement between mobile carriers of quantum information. Such gates have thus far been exclusively realized in the optical domain and by relying on post-selection. Here, we present a non-post-selected, deterministic, photon-photon gate in the microwave … WebMay 11, 2024 · (a) Scheme of the gate. The control (target) photon pulse travels through the setup from left to right (right to left). Polarizing beam splitters (PBSs, blue squares) map between incoming and outgoing polarization qubits and internal dual-rail qubits. One rail of each qubit impinges on the cavity, and the other rail bypasses the cavity. cisd isd
