Recently, magnons (units of electron spin excitation waves) have been considered for information processing. Especially, utilizing thermally excited energetic magnons have been of interest. In parallel, the demand for faster and energy-efficient electronic devices has brought attention to quantum devices using quantum spin state in diamond, which can surpass conventional performance. Now, researchers have successfully measured thermal magnon currents mediated by coherent magnon with a tiny diamond quantum sensor, paving the way for the realization of a hybrid system of quantum spin states and thermal spintronic devices.
