<ul><li>Researchers in Austria and Spain have achieved the creation of Schrödinger cat states, which are superpositions of quantum states, in 'hot' environments with temperatures up to 1.8 K.</li><li>Traditionally, cat states required quantum particles to be in their ground state, which is highly challenging and limits their applications.</li><li>The new study challenges this notion by using thermally excited states, showing that cat states can exist at higher temperatures of up to 1.8 K.</li><li>The research has potential benefits for quantum computing, quantum sensing, and quantum error correction.</li></ul>
