Researchers introduced Monarq, a quantum framework merging QCrank encoding with EHands protocol to perform polynomial transformations on NISQ devices, demonstrating practical quantum data processing. The framework enables key signal and image processing tasks—convolution, discrete-time Fourier transforms (DFT), squared gradient computation, and edge detection—on near-term quantum hardware. Experiments validate Monarq’s functionality despite NISQ-era noise, positioning it as a foundational tool for quantum-enhanced data analysis in real-world applications. Authors Jan Balewski, Roel Van Beeumen, E. Wes Bethel, and Talita Perciano published the work in March 2026, targeting quantum computing’s transition from theory to applied use cases. Monarq’s modular design offers reusable quantum building blocks, accelerating development of hybrid quantum-classical algorithms for image and sequence processing tasks.

This framework provides fundamental quantum building blocks for signal and image processing tasks, including convolution, discrete-time Fourier transform (DFT), squared gradient computation, and edge detection, serving as a reference for a broad class of data processing applications on near-term quantum devices.
