Covers the transition from state-vector to density-matrix formalism, then adds energy relaxation (T1) and pure dephasing (T2) via Lindblad collapse operators. Includes complete Python code using mesolve, comparison plots of ideal vs. open-system dynamics, and purity tracking over time. Connects the simulation to real quantum technology limitations in computing, sensing, and communication. ## Full article daily.dev links to this article rather than hosting it.
