Two-colour high-purity Einstein-Podolsky-Rosen photonic state
Tulio Brito Brasil, Valeriy Novikov, Hugo Kerdoncuff +2
Entanglement is the backbone of quantum information science and its applications. Entangled states of light are necessary for distributed quantum protocols, quantum sensing and qua…
Quantum frequency conversion of vacuum squeezed light to bright tunable blue squeezed light and higher-order spatial modes
Hugo Kerdoncuf, Jesper B. Christensen, Mikael Lassen
Quantum frequency conversion, the process of shifting the frequency of an optical quantum state while preserving quantum coherence, can be used to produce non-classical light at ot…
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…
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…
Experimental Investigation of the Evolution of Gaussian Quantum Discord in an Open System
Lars S. Madsen, Adriano Berni, Mikael Lassen +1
Gaussian quantum discord is a measure of quantum correlations in Gaussian systems. Using Gaussian discord we quantify the quantum correlations of a bipartite entangled state and a…
Continuous variable quantum key distribution with two-mode squeezed states
Lars S. Madsen, Vladyslav C. Usenko, Mikael Lassen +2
Quantum key distribution (QKD) enables two remote parties to grow a shared key which they can use for unconditionally secure communication [1]. The applicable distance of a QKD pro…
