A Diagnostic Framework for Quantum Noise Channels in Single-Qubit Cyber-Physical Systems

Single-qubit channels provide a controlled setting for comparing how different noise mechanisms change a quantum state. Using density matrices and Kraus operators, this paper compares bit-flip, phase-flip, depolarising, amplitudedamping, and phase-damping channels under the same set of input states and diagnostic metri...
