Entangled Photons & Bell’s Test

About this simulation

An ideal polarization singlet is compared with a defined local shared-angle model. Settings are randomly selected independently of the source. Measured S appears after 30 pairs per setting; ± denotes one approximate standard error. This samples theoretical predictions, not evidence from real hardware. Correlations cannot send a message faster than light.

What students can explore

  • Compare the two source models at the default angles. Collect several thousand pairs and examine both local frequencies.
  • Each detector is locally random. Joint correlations can give a CHSH value above the local bound of 2, with a quantum maximum of 2√2.

Learning objectives

  1. 1Compare the two source models at the default angles. Collect several thousand pairs and examine both local frequencies.
