Researchers at ITMO have shown that individual atoms can be transformed into polaritons — quantum particles that are a mixture between matter and light, which are transmitted via optical fibers. The research may have applications in quantum computing in the form of quantum memory.
The researchers previously used techniques that subject matter to high-intensity light beams; the most common method uses optical resonators that let light in but don’t let the photons out easily. The photons are repeatedly reflected from the inner walls of the resonator, constantly interacting with the atoms inside.
After being bombarded with photons, the atoms form bonds with them, facilitating the creation of the quasiparticles.
