The year 2025, designated as the International Year of Quantum Science and Technology, underscores the growing importance of quantum technologies as transformative emerging fields. It is becoming increasingly clear that signal processing (SP), augmented by advances in artificial intelligence (AI), will play a pivotal role in enabling the practical realization and large-scale deployment of quantum sensing, communications, and computing. Conversely, the unique properties of quantum systems—such as superposition and entanglement—offer revolutionary advantages for signal processing itself, providing new frameworks for enhanced detection, faster computation, and secure information transfer. In quantum sensing, tailored SP techniques applied across the entire operational pipeline—from data acquisition to final inference—are essential for achieving reliable performance in industrial applications. AI-enhanced SP methods for denoising, forward- and inverse-modelling, data fusion, parameter estimation, source separation, and control are already being actively employed to advance this domain. A similar synergy between SP and AI in quantum computing and quantum communication are also becoming imperative for enhancing tasks like error mitigation, calibration, protocol improvements, and so on. As the quantum revolution accelerates, the integration of quantum and hybrid processing strategies, including quantum signal processing and machine learning, offers promising avenues alongside their classical counterparts. Europe’s strong commitment to quantum technologies, exemplified by the Quantum Flagship initiative, further emphasizes the need for deeper collaboration between the SP and quantum communities. The 1st Workshop on Signal Processing for Quantum Technologies (SPQT), organized as a half-day satellite event at EUSIPCO 2026, thus aims to provide a timely platform to connect these communities, foster interdisciplinary exchange, and accelerate progress.
The workshop will bring together researchers, practitioners, students, and domain experts to share methodologies, insights, and results demonstrating how SP—including data-driven approaches—can enhance quantum technology implementations and and, in turn, how quantum advancements can redefine the future of signal processing.
