Researchers have pulled off a quantum feat that defies traditional expectations—they’ve created Schrödinger cat states not from ultra-cold ground states, but from warm, thermally excited ones. Using a superconducting qubit setup, the team demonstrated that quantum superpositions can exist even at higher temperatures, overturning the long-held belief that heat destroys quantum effects. This breakthrough not [...]from SciTechDaily https://ift.tt/zIA4cyP
