Researchers at Aalto University linked a time crystal to an external system for the first time. This breakthrough could lead to highly precise sensors and improved memory systems for quantum computers.

Time crystals are special systems that can exist without needing energy from outside. They were first proposed by physicist Frank Wilczek in 2012. In 2016, scientists confirmed their existence experimentally. Now, researchers at Aalto University have connected a time crystal to an external system for the first time.

The team used radio waves to create magnons in a superfluid cooled to near absolute zero. The magnons organized themselves into a time crystal that continued moving for several minutes before fading away. As it weakened, the time crystal interacted with a nearby mechanical oscillator.

This breakthrough is significant because it allows researchers to control and tune the behavior of time crystals. This could lead to new technologies like highly precise sensors or improved memory systems for quantum computers.

The team's findings were published in Nature Communications. They used the Low Temperature Laboratory at OtaNano, Finland's national infrastructure for nano-, micro- and quantum technologies.
