Full Title or Meme
When two or more subatomic particles have a shared set of future attributes, they are consider to be Entangled.
Context
This characteristic of Quantum Mechanics was first noted by Schrödinger and Einstein in the early days of the development of Quantum theory.[1] Very few physicists worried about this until John Bell published a paper defining Local Realism in a way that could be tested.[2] Many scientists (and philosophers) have tested the concept of Local Realism, since it appears to be required by relativity, but is is quite clear now that it is a theory that has been conclusively falsified. This does, if fact, prove that quantum mechanics, as understood in the early years, is incomplete. Which is what Einstein claimed in the EPR paper.[3]
Where do We go from Here?
While the future attributes of Entangled particles is shared, that does not at all mean that the values of these attributes can be known in advance. In fact, QM actually states that only the probability of the outcome of any measurement can be known in advance.
These quantum correlations seem to appear somehow from outside space-time, in the sense that there is no story in space and time that explains them,” says Nicolas Gisin at the University of Geneva, Switzerland. So we seem to be left with the obvious question, which came first: Space-Time or Entanglement?
Non-Locality and Outside Space-Time
- Quantum correlations defy our classical understanding of causality and locality.
- When Alice and Bob’s entangled particles communicate instantaneously, it’s as if information travels outside the usual bounds of space and time.
- However, this doesn’t necessarily mean that information is violating the cosmic speed limit—it’s more about our perception of space and time.
Quantum Information and Spacetime Emergence
Some theories propose that spacetime itself emerges from underlying quantum information.
- In this view, entanglement and quantum correlations are fundamental, and spacetime arises as a consequence.
- Think of spacetime as a cosmic dance floor where particles tango, and entanglement is their intricate choreography.
