This research proposes Quantum-PROBE, a novel framework for blind Angle of Arrival (AoA) estimation in quantum-enhanced sensing systems, addressing the challenge of recovering directional information from phaseless intensity measurements when the optical system's lens response is unknown. The method combines quantum state tomography with compressive phase retrieval and blind deconvolution, achieving robust AoA estimation without prior knowledge of the point-spread function. Theoretical guarantees are established, showing Heisenberg-limited precision scaling even in the presence of unknown aberrations, with a comprehensive experimental validation plan.
