Amplification of realistic cat-like states by homodyne heralding
Amine Laghaout, Jonas S. Neergaard-Nielsen, Ioannes Rigas +3
We present a scheme for the amplification of Schrodinger cats that collapses two smaller states onto their constructive interference via a homodyne projection. We analyze the perfo…

Displacement-enhanced entanglement distillation of single-mode-squeezed entangled states
Anders Tipsmark, Jonas S. Neergaard-Nielsen, Ulrik L. Andersen
It has been shown that entanglement distillation of Gaussian entangled states by means of local photon subtraction can be improved by local Gaussian transformations. Here we show t…
