The results open the path for investigations towards the control of the non-classical states, exploiting conditioning approaches on physical processes relevant to high-harmonic generation. The quantum state of the fundamental mode after the interaction, when conditioned on the high-harmonic generation, is a so-called Schrödinger cat state, which corresponds to a superposition of two distinct coherent states: the initial state of the laser and the coherent state reduced in amplitude that results from the interaction with atoms. This was achieved by using the process of high-harmonic generation in atoms 4, 5, in which the photons of a driving laser pulse of infrared frequency are upconverted into photons of higher frequencies in the extreme ultraviolet spectral range. Here we demonstrate that intense laser–atom interactions may lead to the generation of highly non-classical light states. However, the quantum nature of the electromagnetic fields is always present 3. It’s pathetic.The physics of intense laser–matter interactions 1, 2 is described by treating the light pulses classically, anticipating no need to access optical measurements beyond the classical limit. Everyone just keeps referring to it as ‘Schrodinger’s Cat’. “Erwin dedicated his Nobel Prize to that cat, and now no one can remember the things name. “You have to know things to be a physicist, and not remembering something as simple as a cat’s name is unacceptable,” claims Shepard. “First this, then what next? It’s like physics is entering the dark ages.” “Sadly, this may be one those bits of history that just gets lost,” says Edward Shepard of the Los Alamos National Institute for Physics. And during this experiment Schrodinger called his cat by its name some nineteen times, yet according to the latest data available not a single scientist was able to correctly name the most famous cat in the history of physics.Ī reward has been offered in hopes that someone will come forward to help solve the mystery, but scientists are losing hope. The experiment is quite famous, there’s even a Wikipedia page about it and everything. Erwin Schrodinger once made a great point about quantum physics, something an average person could understand, by using his cat in an experiment.
