Researchers managed to integrate quantum states into conventional electronic devices from silicon carbide and control them with electricity.
A gradual decrease in electronic components of the techniques led to the fact that they reached the fundamental limits and face strange rules for the behavior of particles at the atomic level. Although quantum technologies are considered too delicate to coexist with commercial electronics, but scientists from the University of Chicago reported a breakthrough in this direction.
In two works, they demonstrated that it is possible not only to create quantum states in the components of silicon carbide, but also electrically control them.
The quantum states observed with them, among other things, radiated photons with a wavelength close to the telecommunications range, which allows them to transmit them from existing fiber optic networks over long distances. Using this feature, the team created a «quantum FM radio», which works on the principle of a classic radio transmitter, but with quantum information.
Scientists also found that the use of electric fields removes electrons from the system and stabilizes it. They claim that they solved the problem of ambient noise (interference) with the help of an ordinary diode, which cleared the signal and made it almost perfectly stable.
According to the researchers, uniting the strange physics of quantum mechanics with well-developed classical semiconductor technologies, you can create a new class of devices, without the need to use superconducting metals, levitized atoms or
