Quantum states created in everyday electronics

Scientists at the University of Chicago’s Pritzker School of Molecular Engineering announced a significant breakthrough: Quantum states can be integrated and controlled in commonly used electronics devices made from silicon carbide.

In two papers published in Science and Science Advances, the team demonstrated they could electrically control quantum states embedded in silicon carbide. The breakthrough could offer a means to more easily design and build quantum electronics—in contrast to using exotic materials scientists usually need to use for quantum experiments, such as superconducting metals, levitated atoms or diamonds.

These quantum states in silicon carbide have the added benefit of emitting single particles of light with a wavelength near the telecommunications band. More, by using one of the basic elements of electronics, the diode, the team discovered that the quantum signal suddenly became free of noise and was almost perfectly stable. (Phys.org)
