Is Quantum Teleportation Possible Through Electron-Positron Annihilation?

Click For Summary
SUMMARY

The discussion centers on the feasibility of achieving quantum teleportation through electron-positron annihilation, specifically by directing the resulting gamma rays for pair production. Participants clarify that this method does not qualify as quantum teleportation since the resultant particle pair does not replicate the state of the original pair. True quantum teleportation requires the use of shared Bell pairs to transfer qubit states, which is not accomplished in the proposed scenario. Additionally, the challenges of directing gamma rays due to their properties are highlighted, questioning the practicality of the method.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly quantum teleportation.
  • Familiarity with electron-positron annihilation and its implications in particle physics.
  • Knowledge of Bell pairs and their role in quantum information transfer.
  • Basic concepts of gamma radiation and its behavior in different mediums.
NEXT STEPS
  • Research the principles of quantum teleportation and the role of Bell pairs in qubit transfer.
  • Study electron-positron annihilation and its applications in quantum physics.
  • Explore the properties of gamma rays and methods for directing high-energy photons.
  • Investigate the concept of pair production and its relevance in quantum mechanics.
USEFUL FOR

Physicists, quantum computing researchers, and students of advanced quantum mechanics who are interested in the nuances of quantum teleportation and particle interactions.

Hi
Would it be possible to force an electron and a positron to meat each other and annihilate, then the gamma beam created is to be directed some distance away and passed next to an atom for pair production to occur. ( I dismissed complications related to the vacuums and the magnetic fields).
So according to this system we have teleportated an electron positron pair?

Quantum teleportation turns a classical channel into a quantum channel by consuming previously shared bell pairs. It let's you move qubits/spins/whatever via indirect means. See this video.

Your situation doesn't count as quantum teleportation because the resulting pair is not caused to be in the same state as the input pair (e.g. matching spins). If you managed to work around this and somehow encode those states into the photon, then the photon is a quantum channel (instead of a classical channel) and the process again would not match what people are talking about when they say "quantum teleportation".
 
Ok, would it then be categorised as just teleportation since its definition is: " the transfer of matter or energy from one point to another without traversing the physical space between them."?
And would it even be possible? I said the gamma rays produced must be 'directed'; since gamma rays don't refract or reflect how would it be directed? Does it have to split to smaller energies (lower frequencies) so it can undergo total internal reflection in an optical fibre?
Thanks
