Quantum science studies natural phenomena of light and matter at the smallest scales. Recently, scientists made a groundbreaking discovery that offers new insights to develop the next generation of quantum-based optical and electronic devices more efficiently. Scientists from the University of Minnesota Twin have come up with a unique process to produce a quantum state that is part light and part matter.
Using the process, scientists were able to achieve ultrastrong coupling” between infrared light (photons) and matter (atomic vibrations) by trapping light in tiny, annular holes in a thin layer of gold. These holes were as small as two nanometers, or approximately 25,000 times smaller than the width of a human hair.
These nanocavities, similar to a highly scaled-down version of the coaxial cables used to send electrical signals (like the cable that comes into your TV), were filled with silicon dioxide, which is essentially the same as window glass. Unique fabrication methods, based on techniques developed in the computer-chip industry, make it possible to produce millions of these cavities simultaneously, with all of them simultaneously exhibiting this how much do computer scientists make photon-vibration coupling.
