Coherent Logic Gate for Light Pulses based on Storage in a Bose-Einstein Condensate

Christoph Vo, Stefan Riedl, Simon Baur +2

A classical logic gate connecting input and output light pulses is demonstrated. The gate operation is based on three steps: First, two incoming light pulses are stored in a Bose-E…

Quantum-Dense Metrology

Sebastian Steinlechner, Jöran Bauchrowitz, Melanie Meinders +3

Quantum metrology utilizes entanglement for improving the sensitivity of measurements. Up to now the focus has been on the measurement of just one out of two non-commuting observab…

A cold-atom quantum simulator for SU(2) Yang-Mills lattice gauge theory

Erez Zohar, J. Ignacio Cirac, Benni Reznik

Non-abelian gauge theories play an important role in the standard model of particle physics, and unfold a partially unexplored world of exciting physical phenomena. In this letter,…

Topological Phenomena in Trapped Ion Systems

T. Shi, J. I. Cirac

We propose and analyze a scheme to observe topological phenomena with ions in microtraps. We consider a set of trapped ions forming a regular structure in two spatial dimensions an…

Security of continuous-variable quantum key distribution against general attacks

Anthony Leverrier, Raúl García-Patrón, Renato Renner +1

We prove the security of Gaussian continuous-variable quantum key distribution against arbitrary attacks in the finite-size regime. The novelty of our proof is to consider symmetri…

Lower Bound of Multipartite Concurrence Based on Sub-quantum State Decomposition

Xue-Na Zhu, Ming-Jing Zhao, Shao-Ming Fei

We study the entanglement of tripartite quantum states and provide analytical lower bound of concurrence in terms of the concurrence of sub-states. The lower bound may improve all…
