Abstract: A method of communicating a classical message M between a first party A and a second distant party B over a public channel F, comprises the steps of sharing a key between the parties, the shared key K comprising a short-term-secure key KS and/or a long-term-secure key KL; at A, encoding M as a quantum codeword, A using K to encode M into a first encrypted codeword belonging to a publicly known quantum code; communicating the first encrypted codeword from A to B over F whose output is a second codeword; unitarily transforming the second codeword into a third codeword by using a N-mode interferometer controlled by B, placed at the output of F and keyed by K; determining an estimate of M, at B, by performing a measurement on the third codeword and by processing the measurement using K.

Abstract: A reflecting cell including at least two substrates each covered by an electrode and facing each other, the substrates delimitating between them a volume which separates them and which is filled with a bistable liquid crystal-type material with a threshold field, for example a cholesteric liquid crystal, both electrodes being intended to be connected to a voltage source. This cell is characterized in that at least one of the electrodes is formed by associating a pattern, which does not entirely cover the surface of the substrate considered, and a conducting layer which covers the surface of the substrate considered, the conductivity of the material of the layer being lower than that of the material of the pattern.

Abstract: Methods, systems, and computer program products for decoding a received data signal in a communication system by iteratively constructing a decoding tree, each node of said decoding tree corresponding to a component of a symbol of said data signal, and being associated with a metric, the construction of the decoding tree implementing at least one iteration of the following steps, for a current node of the tree stored in the top of a stack: generating (102) a reference child node of said current node from said vector representing the received data signal, from the reference child node, generating (106) a first neighbor child node by subtracting a positive integer parameter from the value of the reference node, and a second neighbor child node by adding said positive integer parameter to the value of the reference child node; storing (108) in said stack three child nodes deriving from the reference child node and from said first and second neighbor child nodes, each child node being stored in the stack in association with node information comprising a predetermined metric, the nodes in the stack being ordered by increasing values of metrics; removing (109) the current node from said stack; selecting (111) the top node of said stack as the new current node; wherein said method further comprises determining an estimation of said data signal from the node information stored in said stack.

Abstract: The invention relates to a mode selection method for a system for MIMO transmission on an optical fiber of multimode type. It comprises a step of measuring the transfer matrix of the transmission channel made up of a set of modes of the optical fiber (110), a step of transforming (120) the transfer matrix into a block diagonal matrix, each block being associated with a mode subset, a step of determining (130) the gain and/or the transmission capacity for each of the mode subsets, and a selection (140) of the mode subset corresponding to the highest gain and/or capacity, the MIMO transmission system then using only the modes of the subset thus selected to transmit on the optical fiber.The invention relates also to a core selection method for a system for MIMO transmission on optical fiber of multicore type.

Abstract: Embodiments of the invention provide a decoder (10) for decoding a signal received through a transmission channel in a communication system, the signal carrying information symbols selected from a given set of values and being associated with a signal vector, the transmission channel being represented by a channel matrix. The decoder comprises : a sub-block division unit (12) configured to divide the received signal vector into a set of sub-vectors in correspondence with a division of a matrix related to said channel matrix ; at least one weighting coefficient calculation unit (14) configured to calculate a sub-block weighting coefficient for each sub-vector, at least one symbol estimation unit (11) for recursively determining estimated symbols representative of the transmitted symbols carried by the data signal from information stored in a stack. The at least one symbol estimation unit is configured to apply at least one iteration of a sequential decoding algorithm, the sequential decoding algorithm comprising iteratively filling a stack by expanding child nodes of a selected node of a decoding tree comprising a plurality of nodes, each node of the decoding tree corresponding to a candidate component of a symbol of at least a part of the received signal and each node being assigned an initial metric. The symbol estimation unit is further configured to calculate a modified metric for at least one node of the expanded child nodes from the metric associated with the at least one node and from the sub-block weighting coefficient calculated for the sub-vector to which the at least one node belongs, symbol estimation unit being configured to assign the modified metric to the at least one node.

Abstract: A scleral lens that includes a cover part suitable for covering the pupil, the iris and, at least partially, the sclera of an eye of an individual. The cover part includes a transparent central portion. At least one electronic component is encapsulated in a portion of the cover part. A lens in which the form and/or the dimensions of the cover part are configured, at least locally, as a function of the arrangement of the electronic component or components and, if appropriate, of the non-axis symmetrical form of the eye, such that the pupil is totally visible through the transparent central portion of the cover part, when the lens is worn by the eye.

Abstract: The receiver includes a sampler designed to provide one or more samples (yn) per received symbol, the symbols belonging to a predefined alphabet; an equalizer designed to compute, for each received symbol, an estimate (zn) of this symbol based on a linear combination (y′n) of the samples (yn) for this symbol; and a decision module designed to determine the symbol of the alphabet closest to the estimate (zn) as detected symbol. The alphabet exhibits a decentering such that the transmitted symbols have a non-zero predefined expectation, and the equalizer is designed to add a non-zero scalar component (θ) to the linear combination (y′n) in order to compensate at least partially for the decentering.
