In a landmark achievement, Chinese scientists have directly observed and manipulated prethermalisation – a critical transitional state in quantum systems – using the 78-qubit “Chuang-tzu 2.0” superconducting processor.
This allows researchers to “tune” the speed of quantum decoherence, providing a vital tool for managing complex quantum environments.
If a quantum system is disturbed, it naturally returns to a balanced state. The energy and information within it spreads out until they are evenly…
