High-rate quantum cryptography in untrusted networks
Stefano Pirandola, Carlo Ottaviani, Gaetana Spedalieri +6
We extend the field of continuous-variable quantum cryptography to a network formulation where two honest parties connect to an untrusted relay by insecure quantum links. To genera…
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…
Gaussian error correction of quantum states in a correlated noisy channel
Mikael Lassen, Adriano Berni, Lars S. Madsen +2
Noise is the main obstacle for the realization of fault tolerant quantum information processing and secure communication over long distances. In this work, we propose a communicati…
Coupling of a Single Quantum Emitter to End-to-end Aligned Silver Nanowires
Shailesh Kumar, Alexander Huck, Yuntian Chen +1
We report on the observation of coupling a single nitrogen vacancy (NV) center in a nanodiamond crystal to a propagating plasmonic mode of silver nanowires. The nanocrystal is plac…
Quantum-enhanced micro-mechanical displacement sensitivity
Ulrich B. Hoff, Glen I. Harris, Lars S. Madsen +5
We report on a hitherto unexplored application of squeezed light: for quantum-enhancement of mechanical transduction sensitivity in microcavity optomechanics. Using a toroidal sili…
High Fidelity Teleportation of Continuous Variable Quantum States using Delocalized Single Photons
U. L. Andersen, T. C. Ralph
Traditional continuous variable teleportation can only approach unit fidelity in the limit of an infinite (and unphysical) amount of squeezing. We describe a new method for continu…
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…
