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 …

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 …
