Single-Photon 360° Spin Jitter Range Measurement Study (V3)

The intrinsic transverse spin jitter range of photons lacks standardized, reproducible measured control data. This paper constructs a brand-new control experimental system, adopting four groups of comparative experiments: unobstructed free light spot, continuous light beam with single polarizer, free flight of single photons, and single photons with single polarizer. Only a single polarizer is used to unilaterally constrain the vibration components of photons. The experiments cover full-band photons including microwaves, infrared rays, visible light, ultraviolet rays and X-rays. A high-sensitivity receiving plate is adopted to collect the two-dimensional distribution of photon landing points. By comparing the dispersion scale difference of light spots along the X and Y axes under two working conditions (with or without polarization constraint, continuous light beam / single photon), the diffusion noise generated by multi-photon superposition is quantitatively separated, and a calculation method for back-deducing the intrinsic spin jitter amplitude of photons based on the XY amplitude difference is established. Existing physical theories have derived theoretical numerical ranges of photon vibration amplitudes in different wavebands through model deduction. This experiment takes such theoretical intervals as reference standards, and verifies whether the theoretically deduced laws hold through measured data, distinguishing whether deviations originate from experimental systematic errors or defects in the original theoretical model. It fills the research gap of direct measurement of photon vibration range under single polarizer constraint, and provides an operable experimental scheme and quantitative measured data support for the underlying mechanism of photon polarization and basic research on quantum optics.
