THIS “QUANTUM MICROPHONE” CAN LISTEN TO A SINGLE SOUND PARTICLE
Researchers at Stanford University have developed a “quantum microphone” that’s sensitive enough to measure the individual particles of sound known as “phonons.”
“We expect this device to allow new types of quantum sensors, transducers and storage devices for future quantum machines,” said study leader Amir Safavi-Naeini, assistant professor of applied physics at Stanford in a university blog post.
Vibrational Energy
Phonons are individual packets of vibrational energy that often manifest as sound or heat. But measuring individual phonons, according to Stanford, has been impossible until now.
“One phonon corresponds to an energy ten trillion trillion times smaller than the energy required to keep a lightbulb on for one second,” said graduate student Patricio Arrangoiz-Arriola, a co-first author of the study, that was published in the journal Nature
Nanoscale Resonators
Rather than sound moving a membrane inside an ordinary microphone, the quantum microphone uses supercooled resonators, according to Stanford — so small they can only be seen through an electron microscope — that act as a “mirror of sound.”
The device could lay the groundwork for a new way to store information encoded as phonons rather than relying on photons which current quantum computers rely on for encoding information. That could make future mechanical quantum computers even more compact and efficient as phonons are easier to manipulate and have much smaller wavelengths than light particles.
“Sound has this granularity that we don’t normally experience,” Safavi-Naeini said. “Sound, at the quantum level, crackles.”

Normally, it is customary for a technology to mature enough to be used in the field before it can have a military potential.
But here it seems that the situation is different. Although the phonons were not discovered recently, the Russians developed an artillery detection system from 25 km with sound and heat sensors in 2018 before the issue came to the fore. The system was said to enter the inventory by 2020.

As of today, we can say that a new era is about to be opened via ultra-sensitive sound and heat sensors. Quantum microphone technology, like photons, seems to be a candidate for making phonons one of the focal points of technology.
Here we talk about storing phonons instead of storing photons. The use of sound and heat to be stored and processed to say that 20-30 years after the endless opportunities and threats will knock on our door.
A few examples of what kind of future we are facing will be able to listen to the voice of human beings for intelligence purposes from a distance of 10 km.
Stealth technology will now have to be defined from scratch as a result of ultra-sensitization of sound and temperature sensors.
