Quantum Trajectory Data and Codes for a Contextual Stern-Gerlach Analogy

MATLAB codes and data files supporting a theoretical study of a cavity QED analogue to the Stern-Gerlach experiment. The dataset, created by Themistoklis Mavrogordatos, includes quantum trajectory simulations under homodyne and heterodyne detection, with data organized by figure from the associated manuscript. Files contain matrix data for steady-state and conditioned Wigner functions of a cavity field.

Use Cases

• Simulating quantum trajectories under continuous homodyne detection based on the provided MATLAB code Stern_Gerlach.m
• Analyzing the stability of outcomes and spontaneous dressed-state polarization based on data grouped by drive amplitude and local oscillator phase
• Visualizing cavity field fluctuations via Wigner function matrices contained in .mat files like Wss_30.mat
• Studying the bad cavity limit using the included specialized version of the simulation code

Strengths

• Data is explicitly organized by manuscript figure, facilitating direct comparison with published results
• Includes both raw simulation data (.mat files) and the generating MATLAB source code (.m files)
• Covers multiple detection schemes (homodyne and heterodyne) and operational limits (bad cavity)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for some quantitative analyses
• The description is highly technical and assumes prior domain knowledge in quantum optics
