Summary
University of Technology Sydney researchers showed that twisting atom-thin hexagonal boron nitride layers can strongly tune embedded quantum emitters, changing the color and wavelength of the light they produce.
The team repeatedly lifted, rotated and restacked the 2D material, giving continuous control over emission in a way not feasible with more conventional hosts such as diamond or silicon carbide.
The shift was larger than expected, turning hBN’s layered structure into a practical tuning lever for quantum-light components that are often detectable but difficult to make usable.
Published in Science Advances, the work points to more controllable building blocks for quantum computing, secure communications and high-precision sensing applications including healthcare, cybersecurity and GPS.
Can twisting atomic layers scale from the lab to mass-produce future quantum chips?
Will this 'Twistronics' breakthrough render current quantum computing hardware obsolete?
How will this quantum 'twist' reshape the multi-billion dollar race for technological supremacy?
Dynamic Quantum Light Control Achieved via Atomic Twisting of 2D Hexagonal Boron Nitride
Overview
Researchers at the University of Technology Sydney and their collaborators have made a significant breakthrough in quantum light control by introducing a new method that uses mechanical twisting of atomically thin layers of hexagonal boron nitride (hBN). This innovation, published in Science Advances, allows for precise manipulation of quantum light sources, marking a crucial step toward practical quantum technologies. The unique properties of hBN, including its ability to host single-photon emitters that work efficiently at room temperature and its highly tunable layered structure, simplify the design and operation of future quantum devices.
