Ultimate communication capacity of quantum optical channels by solving the Gaussian minimum-entropy conjecture
V. Giovannetti, R. Garcia-Patron, N. J. Cerf +1
Optical channels, such as fibers or free-space links, are ubiquitous in today's telecommunication networks. They rely on the electromagnetic field associated with photons to carry…
A solution of the Gaussian optimizer conjecture
V. Giovannetti, A. S. Holevo, R. Garcia-Patron
The long-standing conjectures of the optimality of Gaussian inputs for Gaussian channel and Gaussian additivity are solved for a broad class of covariant or contravariant Bosonic G…
Fault tolerance for holonomic quantum computation
Ognyan Oreshkov, Todd A. Brun, Daniel A. Lidar
We review an approach to fault-tolerant holonomic quantum computation on stabilizer codes. We explain its workings as based on adiabatic dragging of the subsystem containing the lo…
Continuous-time quantum error correction
Ognyan Oreshkov
Continuous-time quantum error correction (CTQEC) is an approach to protecting quantum information from noise in which both the noise and the error correcting operations are treated…
Logic, Geometry And Probability Theory
Federico Holik
We discuss the relationship between logic, geometry and probability theory under the light of a novel approach to quantum probabilities which generalizes the method developed by R.…
Analysis of circuit imperfections in BosonSampling
Anthony Leverrier, Raúl García-Patrón
BosonSampling is a problem where a quantum computer offers a provable speedup over classical computers. Its main feature is that it can be solved with current linear optics technol…
Using complete measurement statistics for optimal device-independent randomness evaluation
O. Nieto-Silleras, S. Pironio, J. Silman
The majority of recent works investigating the link between non-locality and randomness, e.g. in the context of device-independent cryptography, do so with respect to some specific…
Optimality of Gaussian Discord
Stefano Pirandola, Gaetana Spedalieri, Samuel L. Braunstein +2
In this Letter we exploit the recently-solved conjecture on the bosonic minimum output entropy to show the optimality of Gaussian discord, so that the computation of quantum discor…
The Paraconsistent Logic of Quantum Superpositions
Newton da Costa, Christian de Ronde
Physical superpositions exist both in classical and in quantum physics. However, what is exactly meant by 'superposition' in each case is extremely different. In this paper we disc…
Quadrupole transitions in the bound rotational-vibrational spectrum of the hydrogen molecular ion
Horacio Olivares Pilón, Daniel Baye
The three-body Schrödinger equation of the H hydrogen molecular ion with Coulomb potentials is solved in perimetric coordinates using the Lagrange-mesh method. The Lagrange-m…
Verifying the Steane code with Quantomatic
Ross Duncan, Maxime Lucas
In this paper we give a partially mechanized proof of the correctness of Steane's 7-qubit error correcting code, using the tool Quantomatic. To the best of our knowledge, this repr…
Experimental refutation of a class of ψ-epistemic models
M. K. Patra, L. Olislager, F. Duport +3
The quantum state is a mathematical object used to determine the outcome probabilities of measurements on physical systems. Its fundamental nature has been the subject of discussio…
Silicon-on-insulator integrated source of polarization-entangled photons
Laurent Olislager, Jassem Safioui, Stéphane Clemmen +5
We report the experimental generation of polarization-entangled photons at telecommunication wavelengths using spontaneous four-wave mixing in silicon-on-insulator wire waveguides.…
Equivalence Relations for the Classical Capacity of Single-Mode Gaussian Quantum channels
Joachim Schäfer, Evgueni Karpov, Raúl García-Patrón +2
We prove the equivalence of an arbitrary single-mode Gaussian quantum channel and a newly defined fiducial channel preceded by a phase shift and followed by a Gaussian unitary oper…
A quantum cloning bound and application to quantum key distribution
Erik Woodhead
We introduce a quantum cloning bound which we apply to a straightforward and relatively direct security proof of the prepare-and-measure Bennett-Brassard 1984 (BB84) quantum key di…
Bell nonlocality
Nicolas Brunner, Daniel Cavalcanti, Stefano Pironio +2
Bell's 1964 theorem, which states that the predictions of quantum theory cannot be accounted for by any local theory, represents one of the most profound developments in the founda…
Majorization relations and entanglement generation in a beam splitter
C. N. Gagatsos, O. Oreshkov, N. J. Cerf
We prove that a beam splitter, one of the most common optical components, fulfills several classes of majorization relations, which govern the amount of quantum entanglement that i…
