Quantum Entanglement is a form of quantum superposition. When a measurement is made and it causes one member of such a pair to take on a definite value (e.g., clockwise spin), the other member of this entangled pair will be opposite at any subsequent time.
This leads to many questions in regards to how subatomic molecules behave when under direct observation and also how they behave when not under direct observation. A phenomenon known as the “Observer Effect” in physics, and something more or less defined in quantum mechanics as the “Wave Function Collapse” explains to us that things behave differently while under direct observation of other molecules from a photon in quantum physics, to even small diamonds in standard physics.
Quantum theory takes this to a different level and with the involvement of quantum entanglement, it can assist us in many ways with real-world applications such as the implementation of Solid-State Drives, improvements telecommunication devices, to something even as far-fetched as teleportation. Recent studies have shown that it may in fact be possible for atoms to accelerate faster than the speed of light thanks to quantum entanglement.
This theory as a basic concept states that atoms may in fact be “linked” to one another via an unknown factor. Molecules that are quantically entangled behave in unison, regardless of the distance between, the two molecules will react nearly instantaneously to the other’s. For example, one such behavior in molecules is the spin. If Molecule A located on planet earth has a clockwise spin, then the entangled Molecule B will have a counter-clockwise spin, and could be located on Pluto. Were Molecule A’s spin to change to counter-clockwise, almost instantly Molecule B would change it’s spin accordingly to clockwise. This has excited many theoreticians and inventors because if we manage to unlock the riddles of quantum entanglement and harness it, our world will be forever changed.
