  • Researchers demonstrated that the particles remained unentangled even after being separated by large distances.

Examples

  • What one needs for two marbles is the tensor product of the Hilbert spaces, and the probabilities for conditions "marble 1 does something and marble 2 does something else" reduce to the product of the two individual probabilities if the marbles are unentangled.

  • In quantum physics, two particles are said to be unentangled when their states do not affect each other.

  • I say this is unentangled with the electrons because that's what we started with UDUD and no photon.

  • But if either of the input Phi+ states is replaced by a random unentangled pair of particles, the other is partly randomized, so that neither output pair remains a perfect Phi+.

  • For accurate measurements, we need to ensure that the photons are unentangled from each other.

Morphology

unentangled = entangled (semi-transparent) = un + entangle + ed

The formation is a regular negation: 'un-' + 'entangled' yields 'not entangled'.

Etymology

Unentangled comes from the parts un- ('not') and entangle, which itself has en- ('in') and tangle ('to twist'), so it literally means 'not twisted together'. In quantum physics this gives a clear image: unentangled particles are like two separate ropes lying side by side, each with its own state rather than being joined.
