This work aims to create an engineering-oriented model connecting qubit dynamics to binary outcomes for educational purposes.
Developed a self-contained model integrating open-system dynamics and generalized measurement techniques.
Utilized Lindblad equations and Bloch equations to describe qubit behavior under measurement effects.
Simulated the system using conventional state-space tools and validated it with SPICE.
Demonstrated that measurement-induced dephasing affects coherence decay rates.
Established a quantitative relationship where decoherence influences readout accuracy.
Provided a reproducible validation protocol comparing different theoretical frameworks with practical implementations.
