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.
