In this experiment, the researchers utilized a discrete time crystal as a control mechanism to safeguard the GHZ states within their quantum computer, which consists of qubits made from tiny circuits capable of conducting electricity without resistance. These qubits can exist in a quantum superposition, analogous to Schrödinger’s cat thought experiment, where the cat is simultaneously alive and dead until its state is observed.

Think of it as a control knob for a quantum computer, New Scientist explained.
