MIT Research Shows New Magnetic State That Could Aid Quantum Computing
alphadogg writes "Researchers at MIT and other institutions have demonstrated a new type of magnetism, only the third kind ever found, and it may find its way into future communications, computing and data storage technologies. Working with a tiny crystal of a rare mineral that took 10 months to make, the researchers for the first time have demonstrated a magnetic state called a QSL (quantum spin liquid), according to MIT physics professor Young Lee. He is the lead author of a paper on their findings, which is set to be published in the journal Nature this week (abstract). Theorists had said QSLs might exist, but one had never been demonstrated before. 'We think it's pretty important,' Lee said, adding that he would let his peers be the ultimate judges."
... but we're still very early into this research," Lee said. "It's many, many years away from becoming something that's in a technology that a consumer would use."
Questions raise, answers kill. Raise questions to stay alive.
Look, the Ansible is not possible with quantum entanglement. Also, the original science fiction concept of the Ansible did not involve quantum entanglement. A fictional Ansible is built from a fictional particle that exists simultaneously in two locations and never decays. For an Ansible to work, there must be a special frame of reference in Relativity, but General Relativity does not allow for treating any frame differently from any other frame.
Entanglement is the splitting of a bit of quantum information across two interactions. Neither of the two interactions can possibly have any effect on the other; all that happens is that the entangled measurements from both interactions sum to zero. Every interaction between particles either creates entanglement or destroys it or performs some combination of the two.
Consider that they must sum to zero in every frame of reference under General Relativity: no interaction can determine the results of another because then there would exist some frame of reference where the effect would precede the cause.
That's the bonkers thing about entanglement: it implies determinism but also sidesteps it at the same time.
