Quantum Remote Control...

...and, physicists know how to do it! ~!!!~

TECHNOLOGY REVIEW: Teleportation is one of the more extraordinary phenomena in the quantum world. It allows a quantum object, such as a photon or electron, to travel from one location to another without passing through the space in between.

Teleportation is a standard procedure in any decent quantum mechanics laboratory. Physicists use it on a daily basis for quantum communication and quantum computation.

If that sounds exotic, you ain’t seen nothing yet; teleportation is about to get a whole lot weirder. That’s because until now, physicists have only been able to teleport single particles, one at a time. Today, Christine Muschik at the Mediterranean Technology Park in Barcelona and a bunch of mates say they’ve worked out how to teleport quantum stuff continuously.

That will allow them to manipulate one quantum particle while watching the effects occur in another particle elsewhere. That’s essentially quantum remote control.
