Researchers at Penn State are developing advanced quantum electronics using kink states, which are unique electron pathways in semiconducting materials.

These states could potentially form the backbone of a quantum interconnect network, crucial for transmitting quantum information efficiently. The team has made significant advancements in controlling these states through innovative material combinations and device designs, enhancing the potential for scalable quantum electronics.

The key to developing quantum electronics may have a few kinks. According to a team led by researchers at Penn State, that’s not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials. By controlling the formation of the kink states, researchers can regulate the flow of electrons in a quantum system.
