"Quantum Microphone" Puts Visible Object in Two Places at Once
Abstract:
What is the sound of one molecule clapping? Researchers have demonstrated a device that can pick up single quanta of mechanical vibration similar to those that shake molecules during chemical reactions and have shown that the device itself, which is the width of a hair, acts as if it exists in two places at once. This type of "quantum weirdness" feat so far had only been observed at the scale of molecules.
"This is a milestone," says Wojciech Zurek, a theoretical physicist at Los Alamos National Laboratory. "It confirms what many of us believe, but some continue to resist—that our universe is quantum to the core."
