Generation of Schrödinger cat states

By subtracting a photon from squeezed vacuum states, it is possible to generate (microscopic) Schrödinger cat states

In our publication, Optica Quantum, Vol. 3, No 4/25 August 2025, we achieved for the first time (with a certain probability) the modification of the corresponding measurement data to...

Generation and explanation of the Einstein-Podolsky-Rosen entanglement

Is it possible to predict measurement results without being limited by the Heisenberg uncertainty relation? Yes, but only if you use “EPR” entanglement. There are already various publications on this topic from the working group, e.g., [Zander et al. (2021)].

With his new work Roman Schnabel...
