Characterizing the nonlocal correlations of particles that never interacted
Cyril Branciard, Nicolas Gisin, Stefano Pironio
Quantum systems that have never interacted can become nonlocally correlated through a process called entanglement swapping. To characterize nonlocality in this context, we introduc…
Random Numbers Certified by Bell's Theorem
S. Pironio, A. Acin, S. Massar +8
Randomness is a fundamental feature in nature and a valuable resource for applications ranging from cryptography and gambling to numerical simulation of physical and biological sys…
Purity and Gaussianity bounded uncertainty relation
A. Mandilara, E. Karpov, N. J. Cerf
Bounded uncertainty relations provide the minimum value of the uncertainty assuming some additional information on the state. We derive analytically an uncertainty relation bounded…
Frequency Bin Entangled Photons
L. Olislager, J. Cussey, A. T. Nguyen +4
A monochromatic laser pumping a parametric down conversion crystal generates frequency entangled photon pairs. We study this experimentally by addressing such frequency entangled p…
Quantum dice rolling: A multi-outcome generalization of quantum coin flipping
N. Aharon, J. Silman
We generalize the problem of coin flipping to more than two outcomes and parties. We term this problem dice rolling, and study both its weak and strong variants. We prove by constr…
Entanglement Equivalence of -qubit Symmetric States
P. Mathonet, S. Krins, M. Godefroid +3
We study the interconversion of multipartite symmetric -qubit states under stochastic local operations and classical communication (SLOCC). We demonstrate that if two symmetric…
Security of continuous-variable QKD: exploiting symmetries in phase space
Anthony Leverrier, Evgueni Karpov, Philippe Grangier +1
Proving the unconditional security of a quantum key distribution (QKD) scheme is a highly challenging task as one needs to determine the most efficient attack compatible with exper…
Non-locality and Communication Complexity
Harry Buhrman, Richard Cleve, Serge Massar +1
Quantum information processing is the emerging field that defines and realizes computing devices that make use of quantum mechanical principles, like the superposition principle, e…
Device independent state estimation based on Bell's inequalities
C. -E. Bardyn, T. C. H. Liew, S. Massar +2
The only information available about an alleged source of entangled quantum states is the amount by which the Clauser-Horne-Shimony-Holt (CHSH) inequality is violated: nothing…
Methods for Estimating Capacities and Rates of Gaussian Quantum Channels
Oleg V. Pilyavets, Cosmo Lupo, Stefano Mancini
Optimization methods aimed at estimating the capacities of a general Gaussian channel are developed. Specifically evaluation of classical capacity as maximum of the Holevo informat…
Capacity of a bosonic memory channel with Gauss-Markov noise
Joachim Schäfer, David Daems, Evgueni Karpov +1
We address the classical capacity of a quantum bosonic memory channel with additive noise, subject to an input energy constraint. The memory is modeled by correlated noise emerging…
Continuous wave photon pair generation in silicon-on-insulator waveguides and ring resonators
S. Clemmen, K. Phan Huy, W. Bogaerts +3
Silicon waveguides are promising -based photon pair sources. Demonstrations so far have been based on picosecond pulsed lasers. Here, we present the first investigation of pho…
Population Dynamics in Cold Gases Resulting from the Long-Range Dipole-Dipole Interaction
A. Mandilara, V. M. Akulin, P. Pillet
We consider the effect of the long range dipole-dipole interaction on the excitation exchange dynamics of cold two-level atomic gase in the conditions where the size of the atomic…
Interacting Quantum Observables: Categorical Algebra and Diagrammatics
Bob Coecke, Ross Duncan
This paper has two tightly intertwined aims: (i) To introduce an intuitive and universal graphical calculus for multi-qubit systems, the ZX-calculus, which greatly simplifies deriv…
A quantum de Finetti theorem in phase space representation
Anthony Leverrier, Nicolas J. Cerf
The quantum versions of de Finetti's theorem derived so far express the convergence of n-partite symmetric states, i.e., states that are invariant under permutations of their n par…
Strong no-go theorem for Gaussian quantum bit commitment
Loïck Magnin, Frédéric Magniez, Anthony Leverrier +1
Unconditionally secure bit commitment is forbidden by quantum mechanics. We extend this no-go theorem to continuous-variable protocols where both players are restricted to use Gaus…
Device-independent quantum key distribution secure against collective attacks
Stefano Pironio, Antonio Acin, Nicolas Brunner +3
Device-independent quantum key distribution (DIQKD) represents a relaxation of the security assumptions made in usual quantum key distribution (QKD). As in usual QKD, the security…
Operational Families of Entanglement Classes for Symmetric -Qubit States
T. Bastin, S. Krins, P. Mathonet +3
We solve the entanglement classification under stochastic local operations and classical communication (SLOCC) for all multipartite symmetric states in the general -qubit case.…
