Journal ArticleDOI
A generator for unique quantum random numbers based on vacuum states
Christian Gabriel,Christoffer Wittmann,Denis Sych,Ruifang Dong,Ruifang Dong,Ruifang Dong,Wolfgang Mauerer,Ulrik L. Andersen,Christoph Marquardt,Gerd Leuchs +9 more
TL;DR: Researchers demonstrate random-number generation by exploiting the intrinsic randomness of vacuum states, which may lead to reliable and high-speed quantum random- number generators for applications ranging from gambling to cryptography.
Journal ArticleDOI
Experimental entanglement distillation of mesoscopic quantum states
Ruifang Dong,Mikael Lassen,Mikael Lassen,Joel Heersink,Christoph Marquardt,Radim Filip,Gerd Leuchs,Ulrik L. Andersen +7 more
TL;DR: In this paper, the first time such "entanglement distillation" has been achieved for states of light that are entangled in continuous variables, which should help to increase the distance over which quantum information can be distributed.
Journal ArticleDOI
Experimental demonstration of a Hadamard gate for coherent state qubits
Anders Tipsmark,Ruifang Dong,Ruifang Dong,Amine Laghaout,Petr Marek,Miroslav Ježek,Ulrik L. Andersen +6 more
TL;DR: In this paper, a probabilistic Hadamard gate for coherent state qubits is discussed and an experimental test of the gate for the computational basis is made by full tomographic reconstruction of the transformed output states.
Journal ArticleDOI
Simulations and experiments on polarization squeezing in optical fiber
Joel F. Corney,Joel Heersink,Ruifang Dong,Vincent Josse,Peter D. Drummond,Gerd Leuchs,Ulrik L. Andersen,Ulrik L. Andersen +7 more
TL;DR: In this paper, the authors investigate polarization squeezing of ultrashort pulses in optical fiber, over a wide range of input energies and fiber lengths, and compare experimental data and quantum dynamical simulations to find good quantitative agreement.
Journal ArticleDOI
Experimental evidence for Raman-induced limits to efficient squeezing in optical fibers.
TL;DR: The measured polarization squeezing as a function of optical pulse energy, which spans a wide range from 3.5-178.8 pJ, shows a very good agreement with the quantum simulations, and for the first time the proof experimentally that Raman effects limit and reduce squeezing at high pulse energy is seen.
