Telecom Compatibility Validation of Quantum Key Distribution Co-existing with 112 Gbps/λ/core Data Transmission in Non-Trench and Trench-Assistant Multicore Fibers
Rui Lin, Aleksejs Udalcovs, Oskars Ozolins +12
We experimentally characterize photon leakage from 112Gbps data channels in both non-trench and trench-assistant 7-core fibers, demonstrating telecom compatibility for QKD co-exist…
Tomography from collective measurements
A. Muñoz, A. B. Klimov, M. Grassl +1
We discuss the tomography of -qubit states using collective measurements. The method is exact for symmetric states, whereas for not completely symmetric states the information a…
Experimental quantum tomography assisted by multiply symmetric states in higher dimensions
D. Martínez, M. A. Solís-Prosser, G. Cañas +3
High-dimensional quantum information processing has become a mature field of research with several different approaches being adopted for the encoding of -dimensional quantum sy…
High-dimensional quantum communication complexity beyond strategies based on Bell's theorem
Daniel Martínez, Armin Tavakoli, Mauricio Casanova +3
Quantum resources can improve communication complexity problems (CCPs) beyond their classical constraints. One quantum approach is to share entanglement and create correlations vio…
Tunable entanglement distillation of spatially correlated down-converted photons
E. S. Gómez, P. Riquelme, M. A. Solis-Prosser +4
We report on a new technique for entanglement distillation of the bipartite continuous variable state of spatially correlated photons generated in the spontaneous parametric down-c…
Challenging local realism with human choices
The BIG Bell Test Collaboration, C. Abellán, A. Acín +105
A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglem…
