Quantum entanglement occurs when particles such as photons, electrons, molecules as large as “buckyballs” interact physically and then become separated; the type of interaction is such that each resulting member of a pair is properly described by the same quantum mechanical description (state), which is indefinite in terms of important factors such as position, momentum, spin, polarization, etc.
Now let’s look at Polyamory. substitute the photons, electrons and molecules for relationship partners and accept that the principle is that these partners have been interacting physically. As with all Polyamorous relationships there are many times when all partners are not together at the same time. In fact this is usually the case. Rarely are all three or more partners interacting simultaneously in any one given space at the same given time. Therefore the prescribed separation described in Quantum entanglement takes place often.
In addition, as Communication is a crucial element of Polyamory, the measurement and description of each particle, or partner in this case, is known. It is crucial that each partner is described fully to the other partner so that informed and consensual relationships and entanglements can take place. Therefore when one partner is “measured”, “quantified” and communicated to the other partner there is a subsequent entanglement between the other otherwise none-related partner. There is a knowing.
The measured property of the partner such as their “spin”, as in particles, is known by the interacting partner and is communicated. In addition the “spin” of the other partner is communicated to other partners and finally all partners are aware of the known measured “spins” of all. Even without actually interacting. All partners are then intrinsically entangled again without possibly having met and interacted.
This could be aptly described by the further principle of Quantum “Entanglement Swapping” and the principle of Quantum “Teleportation”.
Teleportation can be applied not just to pure states, but also mixed states, that can be regarded as the state of a single subsystem of an entangled pair. The so-called entanglement swapping is a simple and illustrative example.
If Alice has a particle which is entangled with a particle owned by Bob, and Bob teleports it to Carol, then afterwards, Alice’s particle is entangled with Carol’s.
A more symmetric way to describe the situation is the following: Alice has one particle, Bob two, and Carol one. Alice’s particle and Bob’s first particle are entangled, and so are Bob’s second and Carol’s particle:
Alice-:-:-:-:-:-Bob1 -:- Bob2-:-:-:-:-:-Carol
Now, if Bob performs a projective measurement on his two particles in the Bell state basis and communicates the results to Carol, as per the teleportation scheme described above, the state of Bob’s first particle can be teleported to Carol’s. Although Alice and Carol never interacted with each other, their particles are now entangled.
To pursue this principle in terms of Poly we can illustrate Entanglement Swapping this way:
Bob has two partners. One of his partners, Bob1, is entangled with Alice. The other of Bob’s partners, Bob2, is entangled with Carol. As is often the case, and surely when a fluid bond is sought out, there is a quantification or “measurement” of Bob’s two partners. The information is calculated and transmitted, or “teleported”, to the Alice and Carol and as thus Carol is entangled then with Bob 1, Alice is entangled with Bob 2, and as well, Carol and Alice are also entangled. Even though Alice and Carol may not have interacted at all and even though there may be a significant physical distance between Carol and Alice, just as in the entanglement principle of quantum particles.
The entanglement of the partners or particles was described by Einstein as being “spukhafte Fernwirkung” or “spooky action at a distance”. This is because the entangled particles can influence each other even over a large distance. As such what happens to Alice can effect what happens to Carol and Bob’s partners in the middle and Bob.
This is truly Spooky.
