Physicists have developed a new thermometer that can measure ‘quantumness,’ a term referring to quantum entanglement without disturbing it. This breakthrough challenges the classical understanding of thermodynamics, as it demonstrates that heat can flow from cold to hot objects under certain quantum conditions, defying the second law of thermodynamics.
The innovative device, created by Alexssandre de Oliveira Jr. and his team at the Technical University of Denmark, can detect ‘anomalous heat flow’ at the quantum level, enabling the identification of quantum phenomena like superposition and entanglement without disrupting them. This advancement holds significant implications for quantum computing, as it allows for the verification of genuine quantum calculations and potentially sheds light on quantum aspects of gravity.
