Observing Time Crystals


While the quantum simulation on the IBM quantum computer is still somewhat “noisy” with imperfections or interference, the researchers were still able to observe a time crystal in which the configuration of qubits kept repeating.

Researchers at Australia's University of Melbourne observed a time crystal in action, with the help of quantum computing technology.

Time crystals are a unique arrangement of particles in perpetual, repeating motion in both time and space.

Researchers are studying the use of time crystals as the basis for a new memory device for use with future quantum computers.

When building a time crystal, the individual components must be isolated from the environment to avoid thermalization; the components of quantum computers also need such isolation.

The researchers used IBM's Quantum Hub to turn a quantum computer into a time crystal.

Despite the "noisiness" of the quantum simulation on the IBM quantum computer, the researchers observed a time crystal in which the configuration of qubits perpetually repeated, meaning the system never forgets this initial state, so it never loses its memory.
