Quantum DCT Amplitude Encoding for RGB Image Reconstruction

An independent researcher published a new quantum computing paper in June 2026, introducing a novel method for RGB image reconstruction using quantum amplitude encoding and Qiskit. The study focuses on Quantum Discrete Cosine Transform (DCT) techniques to encode color image data into quantum states, potentially improving efficiency in quantum image processing tasks. The work targets researchers in quantum information, amplitude encoding, and quantum image processing, offering a practical implementation framework using Qiskit’s quantum circuits. The paper is available on Zenodo as a preprint, providing open access to the methodology, code, and experimental results for peer review and further exploration. This development highlights growing independent contributions to quantum imaging, bridging classical image processing techniques with quantum algorithms for potential speedups.
