Researchers have succeeded in integrating quantum states into common silicon carbide electronic devices and electrically controlling them.
The gradual decrease in the electronic components of technology has led to the fact that they have reached fundamental limits and are faced with strange rules for the behavior of particles at the atomic level. Although quantum technology is considered too delicate to coexist with commercial electronics, scientists at the University of Chicago have reported a breakthrough in this direction..
In two papers, they demonstrated that one can not only create quantum states in silicon carbide components, but also electrically control them..
The quantum states they observed, among other things, emitted photons with wavelengths close to the telecommunications range, which allows them to be transmitted over existing fiber-optic networks over long distances. Using this feature, the team created «quantum fm radio», which works on the principle of a classical radio transmitter, but with quantum information.
The scientists also found that applying electric fields removes electrons from the system and stabilizes it. They claim to have solved the problem of ambient noise (interference) by using a conventional diode, which cleaned the signal and made it almost perfectly stable..
By combining the bizarre physics of quantum mechanics with well-developed classical semiconductor technologies, the researchers say, a new class of devices can be created without the need for superconducting metals, levitated atoms or diamonds..
Recall that recently physicists have successfully transmitted quantum entanglement between matter and light over a distance of 50 km using fiber optic cable.
