Abstract
It's not your grandfather's quantum mechanics. Today, researchers treat entanglement as a physical resource: Quantum information can now be measured, mixed, distilled, concentrated, and diluted.
“If two separated bodies, each by itself known maximally, enter a situation in which they influence each other, and separate again, then there occurs regularly that which I have [just] called entanglement of our knowledge of the two bodies.”
—Erwin Schrödinger (translation by J. D. Trimmer)
Erwin Schrödinger coined the word entanglement in 1935 in a three-part paper1 on the “present situation in quantum mechanics.” His article was prompted by Albert Einstein, Boris Podolsky, and Nathan Rosen’s now celebrated EPR paper that had raised fundamental questions about quantum mechanics earlier that year.
