(ScienceDaily) Researchers at the U.S. Naval Research Laboratory (NRL) developed a new technique that could enable future advancements in quantum technology. The technique squeezes quantum dots, tiny particles made of thousands of atoms, to emit single photons (individual particles of light) with precisely the same color and with positions that can be less than a millionth of a meter apart.
“This breakthrough could accelerate the development of quantum information technologies and brain-inspired computing,” said Allan Bracker, a chemist at NRL and one of the researchers on the project.
“NRL’s new method for tuning the wavelength of quantum dots could enable new technologies that use the strange properties of quantum physics for computing, communication and sensing,” Bracker said. “It may also lead to ‘neuromorphic’ or brain-inspired computing based on a network of tiny lasers.”
Applications in which space and power-efficiency are limiting factors may also benefit from this breakthrough approach, researchers said.
