Simulating complex quantum networks with time crystals

Obtaining the associated graph of a 2T-DTC.

Japanese researchers have proposed a method to use time crystals to simulate massive networks with very little computing power.

Time crystals are arrangements of matter that repeat in time. Normal crystals, such as diamonds or salt, repeat their atomic self-organization in space, but do not show any regularity in time. Time crystals self-organize and repeat their patterns in time, meaning their structure changes periodically as time progresses.

The team specifically examined how the quantum nature of time crystals—how they shift from moment to moment in a predictable, repeating pattern—can be used to simulate large, specialized networks, such as communication systems or artificial intelligence.

The researchers plan to explore different quantum systems using time crystals after their approach is experimentally tested. With this information, their goal is to propose real applications for embedding exponentially large complex networks in a few qubits, or quantum bits. (

The study has been published in Science Advances.
