This NSF workshop is dedicated to bring the quantum community and the classical signal processing and information theory community together to explore emerging topics in the intersection of the two fields. The participants will learn advanced signal and information processing techniques and identify new research frontiers in the quantum era.

Workshop Theme

Signal and information processing have long provided the conceptual and algorithmic backbone of modern computing and communications, shaping how we represent, transform, compress, infer, and control information in the presence of noise and resource constraints. As quantum information science matures, these foundational ideas are being reinterpreted in a new regime where signals are quantum states, measurements are intrinsically probabilistic, and hardware spans diverse physical modalities. This workshop explores Signal and Information Processing in the Quantum Era by bringing together the quantum computing community and researchers in classical signal processing and information theory to develop a shared language, identify common principles, and chart emerging research frontiers at their intersection.

A central theme is how quantum resources expand or reshape traditional signal-processing tasks—such as spectral analysis, filtering, estimation, learning, and error mitigation—while respecting quantum limits on information extraction and disturbance. The workshop also highlights opportunities enabled by hybrid quantum platforms that combine discrete-variable systems (e.g., qubits) and continuous-variable systems (e.g., oscillators), motivating “mixed analog–digital” perspectives on quantum signal processing. Through invited talks and interactive discussions, participants will learn advanced techniques spanning quantum signal processing primitives, hybrid encodings and transduction, algorithm–hardware co-design, and information-theoretic performance bounds. The workshop aims to catalyze cross-community collaborations and produce a coherent agenda for scalable, reliable, and application-relevant signal and information processing on near-term and future quantum processors.

Objectives

The main objectives of the workshop are as follows:

• Discuss state-of-the-art research on the following topics: quantum signal processing, continuous-variable quantum systems, and fault-tolerant quantum computing.
• Identify key open problems on how quantum information science can advance or alter the landscape of future information and signal processing techniques in the quantum era.
• Pinpoint the key challenges toward solving these open questions, with the goal of drafting a joint white paper report on these topics from key participants.

The longer term vision is to foster the formation of a new community at the intersection of quantum information science and classical signal processing and electrical engineering. We hope this workshop will be the start of a regular gathering of this new community in the IEEE conferences and fields.

Schedule

The workshop will be 4.5 hours (270 mins) long on Wednesday, September 16, 2026. There will be two sessions (each 80 mins), focusing on quantum signal processing and continuous-variable quantum systems, respectively. Each session will have 1 invited talk and 3 selected contributed talks (20 mins each). This will be followed by a panel discussion (45 mins) and a poster session (45 mins).

The outline of the workshop is as follows (more details to follow):

• Session I, 10:00 AM – 11:30 AM EDT: Quantum Signal Processing
  • Invited (20 mins)
