EPR thought experiment.
- The EPR paper didn't just point out this non-locality issue.
The EPR paper certainly got a lot of attention.
The EPR paper was the first to consider the idea of entanglement.
- The EPR paper by itself had shown that the Copenhagen Interpretation is non-local, which is why Einstein thought there must be an alternative
In the EPR experiment, both theories, Copenhagen Quantum Mechanics and Einstein's local hidden variable alternative make exactly the same prediction.
This is why the EPR paper was set up as a thought experiment because no one had made such an exotic state
Using the EPR argument, the only way for them to coordinate their outcomes is using local hidden variables.
Imagine the EPR thought experiment again, we can think of the entangled state as being in a superposition of the electron being up and the positron down,
And the EPR paper showed that you had to be able to get around the Uncertainty Principle, and if you couldn't, that would mean that either quantum
Thus was born the EPR thought experiment.
I responded to the EPR paper.
This paper is now known as the EPR paper after its authors.
- Bohr said in his reply to EPR , in his multiple replies to EPR , that there is no question of anything non-local going on.
This is the twist on the EPR experiment.
Bohr gave a response to the EPR paper.
And I talk about our brain being EPRAM, Electronically Programmable Random Access Memory, which it kind of is.
Bohr's authority was part of the reason the EPR paper didn't get the attention it deserved.
And so he came up with something called the EPR thought experiment, named after Einstein and his two co-authors on the paper, Podolsky and Rosen.
Bohr however, never forgot about the EPR paper.
In fact, Madam Wu had famously reproduced the EPR thought experiment as a real experiment, but simply doing the EPR experiment in real life isn't
- If you're asking that question and you're playing with the EPR setup, then it's like, oh, it's literally not just figuratively a twist.
There was no need for fast and the like communication to explain the EPR experiment.
And in fact, in an attempt to clear up some of the misunderstandings that people were having about the EPR paper, Schrodinger publishes the thought experiment known
Then Bohr ultimately, you know, in his sort of painful and complicated style ends up coming up with a response to the EPR paper.
So the ultimate reaction of the physics community, at least in the immediate years and decades following the publication of EPR and Bohr's reply in 1935, was to think
He began by re-examining the old debates and the papers that most physicists had long since dismissed as philosophical distractions, including the EPR paper.
And so after more debates between Einstein and Bohr, Einstein put together this thought experiment, the EPR thought experiment.
