Generation of picosecond pulsed coherent state superpositions
Ruifang Dong, Anders Tipsmark, Amine Laghaout +3
We present the generation of approximated coherent state superpositions - referred to as Schrödinger cat states - by the process of subtracting single photons from picosecond pulse…
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…
Experimental test of strongly non-classical character of a noisy squeezed single-photon state
M. Jezek, A. Tipsmark, R. Dong +4
We experimentally verify the quantum non-Gaussian character of a conditionally generated noisy squeezed single-photon state with positive Wigner function. Employing an optimized wi…
Experimental demonstration of a Hadamard gate for coherent state qubits
Anders Tipsmark, Ruifang Dong, Amine Laghaout +3
We discuss and experimentally demonstrate a probabilistic Hadamard gate for coherent state qubits. The scheme is based on linear optical components, non-classical resources and the…
