I just came across the delayed choice quantum eraser experiments (kim et al 1999) through Wheeler's astronomical delayed choice thought experiment and I can't stop thinking about it :-(
I would like to get some ideas on how people interpret this, either the general physics community consensus or your own personal feelings, if you'd be so brave
I keep telling myself that entanglement allows spooky action at a distance in space, so why not over time as well. Still that doesn't get anywhere close to sufficiently rationalising its effects and implications.
So first off, how do we currently reconcile entanglement with relativity if at all?
If I remember my undergrad physics, entanglement is due to QM allowing for superposition of wavestates and nothing more. Do other theories (like string theories) say anything more? Do we think we need a quantised spacetime to understand this?
Does delayed choice break causality (please no)?
Going back to the first question, do we think information is actually being exchanged between measurement events?
What does the Kim experiment suggest about the nature of time?
Thank you
