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 …

Quantum states generation and manipulation in a programmable silicon-photonic four-qubit system with high-fidelity and purity

2024 · APL Photonics

We present a programmable silicon photonic four-qubit integrated circuit for the generation and manipulation of diverse quantum states. The silicon photonic chip integrates photon-pair sources, pump-reducing filters, wavelength-division-multiplexing filters, Mach–Zehnder interferometer switches, and single-qubit arbitrary …
