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 …
