La téléportation quantique est une technique de transfert d'informations quantiques qui consiste à transférer l’état quantique d’un système vers un autre système similaire et distant, sans avoir besoin de transporter physiquement le système lui-même. En d'autres termes, c'est un moyen de transmettre l'information contenue dans un système quantique à un autre endroit, sans avoir à déplacer le système physique.
Quantum 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.
Quantum programming is the process of designing or assembling sequences of instructions, called quantum circuits, using gates, switches, and operators to manipulate a quantum system for a desired outcome or results of a given experiment. Quantum circuit algorithms can be implemented on integrated circuits, conducted with instrumentation, or written in a programming language for use with a quantum computer or a quantum processor. With quantum processor based systems, quantum programming languages help express quantum algorithms using high-level constructs.
L'informatique quantique est le sous-domaine de l'informatique qui traite des calculateurs quantiques et des associés. La notion s'oppose à celle d'informatique dite « classique » n'utilisant que des phénomènes de physique classique, notamment de l'électricité (exemple du transistor) ou de mécanique classique (exemple historique de la machine analytique). En effet, l'informatique quantique utilise également des phénomènes de la mécanique quantique, à savoir l'intrication quantique et la superposition.
Cloud-based quantum computing is the invocation of quantum emulators, simulators or processors through the cloud. Increasingly, cloud services are being looked on as the method for providing access to quantum processing. Quantum computers achieve their massive computing power by initiating quantum physics into processing power and when users are allowed access to these quantum-powered computers through the internet it is known as quantum computing within the cloud.
