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 …

Ensuring superior learning outcomes and data security for authorized learner

2025 · Quantum Science and Technology

Abstract The learner’s ability to generate a hypothesis that closely approximates the target function is crucial in machine learning. Achieving this requires sufficient data; however, unauthorized access by an eavesdropping learner can lead to security …
