A recent article in New Scientist discusses the potential use of time crystals to stabilize quantum computers. Time crystals are a strange state of matter that can flip between two configurations without any energy input. Researchers at the University of Chinese Academy of Sciences have created a control knob for a quantum computer using a discrete time crystal, which oscillates following a pattern in time. By using the time crystal, the researchers were able to increase their control over the quantum computer and minimize disturbances, resulting in a record-breaking Greenberger-Horne-Zeilinger (GHZ) state with 60 qubits. This research has practical implications for making quantum computing and communication applications more stable. [Extracted from the article]
