    they say it could help with research into high-temperature superconductivity but don't explain how so.

    Weird, magnetism governed by brownian movement. Not sure how that is going to turn into technology.

    The work could possibly lead to advances in data storage or communications, he says—perhaps using an exotic quantum phenomenon called long-range entanglement, in which two widely separated particles can instantaneously influence each other's states.

    I know entanglement exists, but I thought it was theoretically impossible to use it to transfer information. Any message must be encoded, and without the encryption key the only random bits are received.

    Or something. What do I know.

    I think you remembered that almost right but you slightly miss-remember. That should be “its theoretically impossible to use it to transfer ( useful ) information over the speed of light

    I get it now. The hope is this potential new tech could use entanglement to improve computing but without sending information faster than light.
