There are fewer and fewer mysteries in the world: Stanford University physicists, for example, have created a quantum microphone and are already studying with it the smallest particles of sound known to science — tiny "portions" of vibrational energy called phonons. It is likely that this microphone will form the basis for the development of quantum computers of the future.
The invention of scientists at Stanford University is innovative in that before its creation, the measurement of phonons was not possible, because the sensitivity of even the most powerful classical microphones is not enough for this — the sound particles are so small that they have minimal impact on the membrane only in a crowd, but not separately. Scientists have developed the device instead of indirect studies of sound wave measures the energy of the phonons directly. For this purpose, tiny resonators are used, which act on the principle of mirrors for sound.
Quantum microphone captures the photons and measures the vibrations caused by them adjusted for the fact that different energy levels correspond to a different number of phonons. Scientists believe that they invented the device can help in creating a fundamentally new type of the quantum computer. It is assumed that the ability to capture such small "portions" of sound will pave the way for the development of devices that can encode information through sound energy. This, in turn, will allow you to store incredible amounts of data on very small media. In theory.
If such a computer is created, it is likely to be much more compact and efficient than quantum computers based on light particles — photons, since sound phonons are much easier to control.
