A few days ago a paper appeared in the physics arXiv that described a clever new faster-than-light signaling scheme. The authors are a pair of Russians from the Lomonosov State University in Moscow, Nikolai Nikitin and Konstantin Toms, who is currently a postdoc at the University of New Mexico after spending time at the ATLAS experiment at CERN. N&T called their paper "Quantum Ansible" after a fictional FTL signaling device in the novels of Ursula LeGuin.

N&T's Quantum Ansible is a more sophisticated realization of my early (1982) FLASH FTL signaling scheme which imagined a universal quantum copying device that could exactly duplicate any unknown quantum state. My FLASH proposal was quickly refuted by Wootters, Zurek and others and led to the discovery/invention of the quantum no-cloning rule which plays an important part in the field of quantum computing.
