The University of Stuttgart has launched the FeedbacQ research project, a three-year initiative aimed at applying control theory to quantum computing. Backed by 1.15 million euros in funding from QuantERA, the project seeks to improve the efficiency and reliability of quantum algorithms.
Why it matters
By integrating continuous measurement and real-time adjustment into the computation process, researchers hope to solve the problem of instability in quantum systems. This approach could accelerate the development of reliable quantum hardware capable of handling complex optimization tasks.
The FeedbacQ project, which was selected from a pool of 287 applications, secured one of 39 funded slots. Researchers will utilize a gate-based quantum device provided by the Politecnico di Torino to test their methods.
The players
University of Stuttgart
A German research university serving as the lead institution for the FeedbacQ project.
QuantERA
A European funding organization supporting collaborative research in quantum technology.
Politecnico di Torino
An Italian technical university providing the gate-based quantum hardware for experiments.
The details
The project uses control theory—the mathematical study of how to influence the behavior of dynamical systems—to manage quantum computations. By implementing continuous measurement and readjustment, the team monitors the algorithm while it runs to correct for errors. This technique allows for the translation of real-world optimization problems into forms optimized for gate-based quantum architectures.
Timeline
2025: FeedbacQ applied for and was awarded QuantERA funding.
October 20, 2026: The FeedbacQ project officially commenced in Berlin.
The Tech Race
FeedbacQ is one of 39 projects selected by QuantERA to advance European quantum capabilities. This effort follows an increasingly crowded field of research aimed at stabilizing quantum gates through active feedback loops.
While this research remains in the lab, it aims to create more reliable quantum computers, which could eventually speed up complex industrial optimization. The project will continue its development cycle over the next three years.
The takeaway
The FeedbacQ project aims to move quantum computing beyond theoretical models into stable, controlled calculation environments. Stakeholders should monitor the team's progress toward the project's conclusion in late 2029 for potential benchmarks on gate-based system reliability.
