Researchers from CNRS and École Polytechnique introduced a dynamic programming principle for quantum filtering in infinite-dimensional Hilbert-Schmidt spaces, advancing control theory for continuously monitored quantum systems. The study focuses on stabilizing Ising-coupled qubits under continuous observation, demonstrating exponential convergence to target eigenstates via feedback laws in the mean-field limit. A key breakthrough is embedding quantum state spaces into Hilbert-Schmidt frameworks, enabling rigorous analysis of quantum state reduction in complex, high-dimensional systems. The team proves quantum state reduction occurs under specific feedback protocols, offering a path to precise quantum state preparation in noisy, monitored environments. This work bridges quantum control and mean-field theory, with potential applications in error-corrected quantum computing and real-time quantum feedback systems.

We then study a stabilization problem for continuously monitored Ising-coupled qubits and, in the mean-field limit, demonstrate quantum state reduction together with exponential convergence toward prescribed eigenstates under suitable feedback laws.
