Quantum information science is a field that combines the principles of quantum mechanics with information science to study the processing, analysis, and transmission of information. It covers both theoretical and experimental aspects of quantum physics, including the limits of what can be achieved with quantum information. The term quantum information theory is sometimes used, but it does not include experimental research and can be confused with a subfield of quantum information science that deals with the processing of quantum information. Quantum teleportation, entanglement and the manufacturing of quantum computers depend on a comprehensive understanding of quantum physics and engineering. Google and IBM have invested significantly in quantum computer hardware research, leading to significant progress in manufacturing quantum computers since the 2010s. Currently, it is possible to create a quantum computer with over 100 qubits, but the error rate is high due to the lack of suitable materials for quantum computer manufacturing. Majorana fermions may be a crucial missing material. Quantum cryptography devices are now available for commercial use. The one time pad, a cipher used by spies during the Cold War, uses a sequence of random keys for encryption. These keys can be securely exchanged using quantum entangled particle pairs, as the principles of the no-cloning theorem and wave function collapse ensure the secure exchange of the random keys. The development of devices that can transmit quantum entangled particles is a significant scientific and engineering goal. Qiskit, Cirq and Q Sharp are popular quantum programming languages. Additional programming languages for quantum computers are needed, as well as a larger community of competent quantum programmers. To this end, additional learning resources are needed, since there are many fundamental differences in quantum programming which limits the amount of skills that can be carried over from traditional programming.

Quantum channel

In quantum information theory, a quantum channel is a communication channel which can transmit quantum information, as well as classical information. An example of quantum information is the state of a qubit. An example of classical information is a text document transmitted over the Internet. More formally, quantum channels are completely positive (CP) trace-preserving maps between spaces of operators. In other words, a quantum channel is just a quantum operation viewed not merely as the reduced dynamics of a system but as a pipeline intended to carry quantum information.

Distribution quantique de clé

L'échange quantique de clé (ou distribution quantique de clé, ou négociation quantique de clé), souvent abrégé QKD (pour l'anglais : quantum key distribution) est un échange de clé, c'est-à-dire un protocole cryptographique visant à établir un secret partagé entre deux participants qui communiquent sur un canal non sécurisé. Ce secret sert généralement à générer une clé cryptographique commune (c'est pourquoi il s'agit d'échange de clé, au singulier), permettant ensuite aux participants de chiffrer leurs communications au moyen d'un algorithme de chiffrement symétrique.
