Controlled-NOT operation of SiN-photonic circuit using photon pairs from silicon-photonic circuit

2021 · Optics Communications

We demonstrate controlled-NOT (CNOT) operation of a silicon nitride photonic integrated circuit using path-entangled photon pairs from a silicon-photonic integrated circuit as logical inputs. The CNOT gate is constructed by combining several silicon-nitride Mach–Zehnder interferometers …

The role of state preparation in time-bin entangled photon pair generation for quantum communication

2024

Time-bin entangled photons have previously been utilized for advanced quantum communication protocols such as quantum state teleportation or entanglement swapping, thus showing the potential of realizing a quantum internet. For such protocols, intricate feedback systems …
