The study authors used a copper oxide gemstone mined in Namibia to create
Scientists used a Fabry-Perot microcavitya system of two parallel mirrors to capture light and form a resonant optical wave. The researchers placed the finished plate between the mirrors. Giant excitons with a principal quantum number of up to 25 and a diameter of up to 1 μm were observed in cuprous oxide.
In the Fabry-Perot resonator, scientists managed to achievestrong binding of light with excitons with a principal quantum number of up to 6 and form the largest exciton polaritons. According to the researchers, their size is about 100 times larger than ever seen before.
Physicists note that Rydberg polaritonsconstantly switching from light to matter and back. Scientists compare these quasi-particles to a coin that has two sides at the same time. It is these sides that allow polaritons to interact with each other.
This interaction is criticalthe authors of the study emphasize, because it is it that allows you to create quantum simulators, a special type of computer where information is stored in quantum bits. These quantum bits, unlike binary bits in classical computers, can take on any value from 0 to 1. Thus, they can store much more information and perform several processes at the same time.
“Creating a quantum simulator with light isThe holy grail of science. We have made a huge leap in this direction by creating Rydberg polaritons, a key component of such simulators,” says Hamid Ohadi, project leader from the School of Physics and Astronomy at the University of St. Andrews.
