Verschränkung is said to be a word coined by Erwin Schrödinger. Entanglement is the approximation of the word in English. I learned this after Schrödinger’s Cat popped up as a character in several recent Dilbert cartoon strips.
Krzysztof Byczuk did a well organized presentation and said this about the concept;
-Entanglement is a quantum correlation in quantum many body
system
-Entanglement does not depend on particular physical representation
-Entanglement is a resource like energy
-Entanglement can be quantified and measured
His 2005 presentation, available here;
– – goes on to point out that the correlations provided by measurements do not constitute superluminal transfer of information or energy, His one sentence summary of the Bell theorem is, “Nature itself is fundamentally non-local, expressed in a subtle correlation between two lists of otherwise random data.”
Schrödinger’s 1935 thought problem involving a cat in an undefined state before measurement is said to be the origin of the word verschränkun. It is certainly possible to suggest that many of the problems we have in understanding the world are the result of the vocabulary and grammar we use as tools as we try to describe it. “We shape our tools and then they ape us” is the first variation on the McLuhan description of the process. The other relevant quote I came across when Googling about on this topic is from Yoko Ono, “A dream you dream alone is only a dream. A dream you dream together is reality.”
And to think all of this text sprung from two recent Dilbert cartoon strips. The boundary between physics and metaphysics gets smaller all the time.
