Twisting Atomically Thin Layers of Hexagonal Boron Nitride Controls Quantum Light Sources
In a paper published in Science Advances, researchers at the University of Technology Sydney (UTS) in collaboration with the University of Minnesota and Kyung Hee University have found a new way to control quantum light sources, which is one of the key elements needed before quantum technologies can be used reliably in real-world systems.
Researchers have discovered a new method to control quantum light sources by twisting atomically thin layers of hexagonal boron nitride (hBN). This breakthrough is a significant step towards reliable quantum technologies like quantum computing and secure communication. The team at the University of Technology Sydney, in collaboration with international partners, found that twisting the layered hBN material allows for substantial shifts in the color and wavelength of emitted light. Unlike traditional materials, hBN's layered and twistable structure provides a unique control mechanism. This technique offers a more significant manipulation range than previously achieved, bringing practical quantum applications closer to reality.
This novel control mechanism for quantum light sources is a key advancement for the practical implementation of quantum technologies.
