Researchers at the University of Technology Sydney have demonstrated a new way to control tiny sources of quantum light by twisting atomically thin layers of hexagonal boron nitride.
The advance provides scientists with a new method for tuning quantum emitters, which are microscopic light sources that could play an important role in future technologies such as quantum computing, secure communications, and ultra-sensitive sensors.
Lead author Dr. Angus Gale said the work offers researchers a valuable new tool for making these quantum systems more practical.
"You can measure these quantum emitters and see that they exist, but it's hard to make them work in practice. This gives us a lever to get closer to that -- a step towards the realization of quantum technologies," said Dr. Gale.
