Researchers at the Rensselaer Polytechnic Institute in the US have made a new quantum simulator device that works at room temperature.

Unlike expensive infrastructure used to study quantum mechanics that can supercool matter in vacuum, this device works at room temperature.A tiny device, thinner than human hair, created by researchers at the Rensselaer Polytechnic Institute in the US, can help scientists explore the nature of light and matter and unlock mysteries of the quantum realm. The technology’s most important prospect is that it works at room temperature and does not need sophisticated infrastructure.

in an email. CsPbCl3 is a perovskite material that the researchers used to make a photonic topological insulator .. From light-emitting diodes to lasers and transistors to electron microscopes, modern technology has been made possible by understanding quantum mechanics. They first grew ultrathin plates of the perovskite using cesium, lead, and chlorine. Then, they etched a polymer with a pattern on top of it. They then sandwiched the crystal plates and polymer between sheets of different oxide materials to get an object about two microns thick and 100 microns long, no wider than an average human hair. When researchers used laser light on the device, it created a glowing triangular pattern on the material’s interfaces.
