Entanglement distillation is the transformation of N copies of an arbitrary entangled state into some number of approximately pure Bell pairs, using only local operations and classical communication (LOCC). Entanglement distillation can in this way overcome the degenerative influence of noisy quantum channels by transforming previously shared less entangled pairs into a smaller number of maximally entangled pairs (Bell states).

Famous quotes containing the words distillation and/or entanglement:
“In this century the writer has carried on a conversation with madness. We might almost say of the twentieth-century writer that he aspires to madness. Some have made it, of course, and they hold special places in our regard. To a writer, madness is a final distillation of self, a final editing down. Its the drowning out of false voices.”
—Don Delillo (b. 1926)
“It would be one of the greatest triumphs of humanity, one of the most tangible liberations from the constraints of nature to which mankind is subject, if we could succeed in raising the responsible act of procreating children to the level of a deliberate and intentional activity and in freeing it from its entanglement with the necessary satisfaction of a natural need.”
—Sigmund Freud (18561939)
