Generalization errorFor supervised learning applications in machine learning and statistical learning theory, generalization error (also known as the out-of-sample error or the risk) is a measure of how accurately an algorithm is able to predict outcome values for previously unseen data. Because learning algorithms are evaluated on finite samples, the evaluation of a learning algorithm may be sensitive to sampling error. As a result, measurements of prediction error on the current data may not provide much information about predictive ability on new data.
Superconducting quantum computingSuperconducting quantum computing is a branch of solid state quantum computing that implements superconducting electronic circuits using superconducting qubits as artificial atoms, or quantum dots. For superconducting qubits, the two logic states are the ground state and the excited state, denoted respectively. Research in superconducting quantum computing is conducted by companies such as Google, IBM, IMEC, BBN Technologies, Rigetti, and Intel. Many recently developed QPUs (quantum processing units, or quantum chips) utilize superconducting architecture.
Non-functional requirementIn systems engineering and requirements engineering, a non-functional requirement (NFR) is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviours. They are contrasted with functional requirements that define specific behavior or functions. The plan for implementing functional requirements is detailed in the system design. The plan for implementing non-functional requirements is detailed in the system architecture, because they are usually architecturally significant requirements.
Quantum networkQuantum networks form an important element of quantum computing and quantum communication systems. Quantum networks facilitate the transmission of information in the form of quantum bits, also called qubits, between physically separated quantum processors. A quantum processor is a small quantum computer being able to perform quantum logic gates on a certain number of qubits. Quantum networks work in a similar way to classical networks. The main difference is that quantum networking, like quantum computing, is better at solving certain problems, such as modeling quantum systems.
Requirements traceabilityRequirements traceability is a sub-discipline of requirements management within software development and systems engineering. Traceability as a general term is defined by the IEEE Systems and Software Engineering Vocabulary as (1) the degree to which a relationship can be established between two or more products of the development process, especially products having a predecessor-successor or primary-subordinate relationship to one another; (2) the identification and documentation of derivation paths (upward) and allocation or flowdown paths (downward) of work products in the work product hierarchy; (3) the degree to which each element in a software development product establishes its reason for existing; and (4) discernible association among two or more logical entities, such as requirements, system elements, verifications, or tasks.
Software requirements specificationA software requirements specification (SRS) is a description of a software system to be developed. It is modeled after the business requirements specification (CONOPS). The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.
Simulation informatiquevignette|upright=1|Une simulation informatique, sur une étendue de , de l'évolution du typhon Mawar produite par le Modèle météorologique Weather Research and Forecasting La simulation informatique ou numérique est l'exécution d'un programme informatique sur un ordinateur ou réseau en vue de simuler un phénomène physique réel et complexe (par exemple : chute d’un corps sur un support mou, résistance d’une plateforme pétrolière à la houle, fatigue d’un matériau sous sollicitation vibratoire, usure d’un roulem
Calcul quantique adiabatiqueLe calcul quantique adiabatique (en anglais, adiabatic quantum computation ou AQC) est une méthode de calcul quantique reposant sur le théorème adiabatique, qui peut être vu comme une sous-classe des méthodes de recuit simulé quantique. On détermine d'abord un hamiltonien complexe dont l'état fondamental décrit une solution du problème étudié. On prépare ensuite un système possédant un hamiltonien plus simple, que l'on initialise dans son état fondamental.
Problème du sac à dosEn algorithmique, le problème du sac à dos, parfois noté (KP) (de l'anglais Knapsack Problem) est un problème d'optimisation combinatoire. Ce problème classique en informatique et en mathématiques modélise une situation analogue au remplissage d'un sac à dos. Il consiste à trouver la combinaison d'éléments la plus précieuse à inclure dans un sac à dos, étant donné un ensemble d'éléments décrits par leurs poids et valeurs.
Algorithme de GroverEn informatique quantique, l’algorithme de Grover est un algorithme de recherche, permettant de rechercher un ou plusieurs éléments qui répondent à un critère donné parmi éléments non classés en temps proportionnel à et avec un espace de stockage proportionnel à . Il a été découvert par Lov Grover en 1996. Dans les mêmes conditions (recherche parmi des éléments non classés), un algorithme classique ne peut faire mieux qu'une recherche dans un temps proportionnel à , en testant successivement le critère sur chaque élément.
