Are Entangled Photons the Same Particle?

Click For Summary
SUMMARY

A pair of entangled photons consists of two distinct photons that share a single wave function, confirming their individuality despite their entangled state. The discussion emphasizes that these photons are not the same particle, as they maintain separate identities while exhibiting correlated behaviors. Various experimental methods exist to demonstrate the properties of entangled photons, reinforcing the understanding of their nature in quantum mechanics.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with the concept of wave functions
  • Knowledge of photon entanglement
  • Basic grasp of experimental physics methodologies
NEXT STEPS
  • Research quantum entanglement experiments
  • Explore the implications of wave function sharing in quantum mechanics
  • Study the role of entangled photons in quantum computing
  • Investigate higher-dimensional theories in physics
USEFUL FOR

Physicists, quantum mechanics students, and researchers interested in the nature of light and quantum entanglement.

Has it or can it be proven whether a "pair" of entangled photons are really the same photon (or not)?

Thanks,

A pair of entangled photons is 2 photons. They share a single wave function. There are a variety of ways to demonstrate this. Can you tell us why you would think that 2 photons are really 1?

It might be used as a basis of trying to understand their nature. Kinda like considering higher dimensions in an effort to unraveling other mysteries in physics.
