I [video] Simulating a delayed choice quantum eraser in an online drag-d

Click For Summary
The discussion focuses on a video simulating a delayed choice quantum eraser experiment, addressing common misconceptions. The creator seeks feedback on how accurately the simulation reflects the actual experiment, acknowledging limitations such as the lack of free space propagation of photons. Participants are invited to consider whether these differences impact the understanding of the experiment's principles. The conversation emphasizes the importance of fidelity in simulations for educational purposes. Overall, the thread explores the balance between simulation accuracy and conceptual clarity in quantum mechanics.

This is a follow-up video I made to a previous one on common misconceptions about the experiment. I'm interested in people's opinions here about how close the simulated experiment is to the real thing (e.g. there have to be some compromises due to the simulator not having free space propagation of photons; they always move in nice clean lines) and whether or not you think the differences "matter".

 

Thread 'The Power of QM and QFT'

We often see discussions about what QM and QFT mean, but hardly anything on just how fundamental they are to much of physics. To rectify that, see the following; https://www.cambridge.org/engage/api-gateway/coe/assets/orp/resource/item/66a6a6005101a2ffa86cdd48/original/a-derivation-of-maxwell-s-equations-from-first-principles.pdf 'Somewhat magically, if one then applies local gauge invariance to the Dirac Lagrangian, a field appears, and from this field it is possible to derive Maxwell’s...
