TEHRAN (IFP) -- An Iranian scientist has invented a quantum microphone that can track the smallest sound packets called phonons.
Amir Safavi Nayini, an assistant professor at Stanford University along with a team of researchers at the university, has devised a quantum microphone that can detect the smallest sound or vibration packets called phonons or phonetic energy quantum. The achievement provides the background for more efficient quantum computers.
Previously it was impossible to track phonons because traditional microphones were not sensitive enough to detect them.
When a sound wave hits a membrane, the microphone detects it. But phonons are very small and cannot be tracked alone.
Instead of relying on acoustic wave measurements, scientists have devised a device that measures the energy of phonons directly using very small resonators that act as a mirror for sound.
A resonator is a device or system that displays a resonance or resonance reaction. It can capture photons and detect the vibrations they emit.
