One of the more elegant explanations of this quantum phenomenon is Schrödinger's Cat.
So, in essence, the cat is both dead and alive; the system is said to be in a state of superposition.
This quantum effect has always been talked about in terms of the atomic or molecular scale, never for macroscale objects.
Now, a team of researchers led by scientists at the Imperial College London has described, in the New Journal of Physics, their ability to measure this quantum effect in a small—yet visible to the naked eye—drum.
The result: the skin of the drum has been made to vibrate and not vibrate at the same time.
The “quantum drum,” according to Michael R. Vanner, principal investigator at Quantum Measurement Lab at Imperial College London, is a tiny mechanical oscillator that is so small and compliant that even the reflection of light can make it move.
