Time leads crystal researchers to future computational work


Time seems like something out of crystal science fiction, but they could be the next major leap in quantum network research. A team based in Japan has proposed a way to use time crystals to simulate large-scale networks with very little computing power.
He published his results on 16 October Science advance.
First theorem in 2012 and observed in 2017, time is an arrangement of crystal matter that repeats in time. Normal crystals, such as diamonds or salts, replicate their atomic self-organization in space, but show no regularity in time. Time crystals self-organize and repeat their patterns in time, meaning that their structure changes over time.
“The discovery of time crystals is a very active area of ​​research and many diverse experimental realizations have been achieved,” said paper author KA Nemoto, professor in the Informatics Research Division of the National Institute of Informatics. “An intuitive and complete insight about the nature of time crystals and their characterization is lacking, as well as a set of proposed applications. In this paper, we provide new tools based on graph theory and statistical mechanics to fill this theory. We do.”
Nemoto and his team specifically investigated how the quantum nature of time crystals – how they change from time to time in a predictable, repeating pattern – is used in large, specialized networks, such as communication systems or artificial Can be done to emulate intelligence.
“In the classical world, this would be impossible because it would require large amounts of computing resources,” said Marta Estrellas, one of the first authors of the paper at the National Institute of Informatics. “We are not only bringing a new method to represent and understand quantum processes, but a different way of looking at quantum computers.”
Quantum computers can store and manipulate multiple states of information, meaning that they can process vast data sets with relatively little power and time by resolving multiple possible outcomes at the same time, much like classical computers. One after the other.
“Can we use this network representation and its tools to understand complex quantum systems and their phenomena, as well as identify applications?” Nemoto asked. “In this work, we show the answer yes.”
Researchers plan to explore various quantum systems using time crystals after experimental testing of their approach. With this information, they aim to propose real applications to embed increasingly large complex networks in a few qubits or quantum bits.
“With multiple qubits using this method, a complex network can simulate the size of the entire world’s Internet,” said Nemoto.
