Oxford physicists have reportedly made a breakthrough related to Schrödinger's cat, creating new quantum states that were previously only theoretical. The exact nature of the discovery is unclear, with some outlets suggesting it involves demonstrating unusual quantum states or creating a new kind of Schrödinger's cat, while others imply it may have broader implications for our understanding of reality and the universe. The findings may also have connections to quantum entanglement and thermodynamics, although the details and scope of the discovery are not entirely clear.
