Can we peek at Schrodinger’s cat without disturbing it?

Science Daily  October 2, 2019 According to an international team of researchers (Japan, India) a camera set up outside a box that has Schrödinger’s cat takes a photo of the cat, and the scientists don’t know whether it is dead or alive. The flash from the camera has removed a “quantum tag” marking the superposition of the cat. The photo is now entangled with the fate of the cat i.e. we can decide what happened to the cat by processing this photo in a certain way. The researchers propose that depending on what method is used to process the photo, […]

Physicists can predict the jumps of Schrodinger’s cat (and finally save it)

Phys.org  June 3, 2019 An international team of researchers (USA – Yale University, New Zealand) used a special approach to indirectly monitor a superconducting artificial atom, with three microwave generators irradiating the atom enclosed in a 3-D cavity made of aluminum. Microwave radiation stirs the artificial atom as it is simultaneously being observed, resulting in quantum jumps. They amplified the tiny quantum signal of these jumps and monitored it in real time which enabled the researchers to see a sudden absence of detection photons which was a warning of a quantum jump. Despite its observation, coherence increased during the jump. […]
