Inside the quantum image recognition engine (IMAGE)
Caption
In their simulated system, image data is first simplified using a process called principal component analysis (PCA), which reduces the amount of information while preserving key features. A complex photonic state is generated, onto which this data is encoded, before being processed in the quantum reservoir —where interference between photons produces rich, complex patterns used for image recognition.
This system requires training only at the final stage—a simple linear classifier—making the overall approach both efficient and effective for accurate image recognition.
