Roland Piquepaille writes "It's an antenna, it's a MEMS device, and it's a macroscopic quantum system. This antenna, made of 50 billion atoms, is so far the largest structure to display quantum mechanical movements. It's also the fastest device of its kind in the world, oscillating about 1.5 billion times per second. Such technology might soon be used in our cell phones. But more importantly, this device bridges classic and quantum physics. Such "mechanical/quantum mechanical hybrids could be used for quantum computing" in the future. Read more for other details, references and a picture showing different views of this world's fastest nanomechanical structure."
