Photonic quantum reservoir computing on real financial surfaces: identifying the structural ceiling of near-random-walk data

Quantum machine learning is increasingly proposed for financial time series, yet practitioners have no way to predict whether quantum reservoir computing (QRC) will outperform classical baselines on a given dataset before committing resources. We propose a pre-experimental screening framework, built on persistence R2...

Hybrid photonic-quantum reservoir computing for time-series prediction

Motivated by the perspective of advanced time-series prediction and exploitation of quantum reservoir computing (QRC), we explored the design and implementation of a hybrid photonic-QRC (HPQRC) paradigm. This brings together the high-speed parallelism of photonic systems with the quantum reservoir’s capacity to model c...
