Tiny pillars put light and sound in a quantum superposition

In recent years, there has been a lot of interest in coupling sound and light together.

Admittedly, we've been doing this for a long time, but we've always been limited in terms of what we can do with how nature puts materials together.

Now, with our ability to construct structures that are the right size, we can make devices that really dance to the tune that we give them.

Researchers have put together micro pillars that convert light into long-lasting, very high-frequency sound waves.

Nature, of course, allows sound and light to play together in different ways.

The blue light excites sound waves in the fiber—these are sound waves with THz (1012Hz) frequencies, while audible sounds are in the kHz range.
