This piece explains why quantum information is so difficult to protect, covering decoherence, the No-Cloning Theorem, and the three fundamental Pauli errors (X bit flip, Z phase flip, Y combined). It introduces quantum channels as an abstraction for modeling noise, explains how continuous errors can be discretized into Pauli operators, and provides an intuition for stabiliser codes — which detect errors by measuring properties of the system rather than the quantum state itself. Python code examples illustrate each Pauli error operation. ## Full article daily.dev links to this article rather than hosting it.
