Structured leakage in OAM-encoded qubits revealed by distributed quantum feature extraction
The research investigates how turbulence degrades Orbital Angular Momentum (OAM) qubits by modeling it as structured leakage from a logical subspace into other modes. By analyzing this structured leakage, the authors developed a distributed quantum feature extraction framework using quantum convolutional operations to identify robust features that remain stable despite turbulence-induced distortions.
