A special type of light made with an ancient Namibian gemstone will power new quantum computers, capable of solving long -term scientific mysteries, according to new research led by the University of St Andrews.

The research, conducted in collaboration with scientists at Harvard University in the US, Macquarie University in Australia and Aarhus University in Denmark and published in Natural Thingsused in a really dug glass (Cu2O) precious stones from Namibia that form the Rydberg polaritons, large fragments of light and artificial materials.

Rydberg polaritons constantly change from light to object back and forth. In Rydberg polaritons, light and matter are the same on both sides of the centimeter, and the matter side is where the polariton interacts with each other.

This relationship is important because it makes it possible to create quantum simulators, a special type of quantum computer, where knowledge is stored in quantum bits. Unlike these quantum bits, unlike binary bits in older computers that could only have 0 or 1, they could carry any value between 0 and 1. So they could hold values. Learn more and perform the procedures at the same time.

This could allow quantum simulators to solve important mysteries of physics, chemistry and biology, for example, how to make high temperature superconductors for high -speed vehicles, how to to fats to solve global hunger, or how proteins can be synthesized in a simple way. make drugs better.

Project leader Dr. Hamid Ohadi, of the School of Physics and Astronomy at St Andrews University, said, “building a quantum simulator with light is the holy grail of science.”

To create the Rydberg polaritons, the researchers recorded the light between two comparison lenses. A glass oxide glass from a rock excavated in Namibia was then melted and rolled into a 30-micrometer thick plate (much thinner than a string of human hair) and sealed between layers. two mirrors produce Rydberg polaritons 100 times larger than previously reported.

One of the great writers was Drs. Sai Kiran Rajendran, of the School of Physics and Astronomy at St Andrews University, said “it is easy to buy stone on eBay.

The company is refining these techniques in order to explore the potential to create quantum circuits, which is new to quantum simulators.
