What does the "monogamy" principle imply? At a superficial level, it seems to say that a particle can be entangled with at most one other particle.
However, I keep reading that several particles are entangled. For example:
Quantum entanglement can reach into the past. Here they describe an experiment with two entangled pairs, (A1,A2) and (B1,B2). Victor is given A2,B2, Alice is given A1 and Bob is given B1. All three are separated by a large distance. If Victor entangles A2,B2 then he has entangled A1 and B1 as well. This somehow implies that each particle can be entangled with more than 1.
3,000 atoms entangled in bizarre state. Scientists somehow entangled ≈ 3000 atoms.
Both imply that entanglement is not monogamous. So what does the "monogamy" principle actually imply?
