Quantum information is the information of the state of a quantum system. It is the basic entity of study in quantum information science, [1][2][3] and can be manipulated using quantum information …

Quantum information science involves using the smallest bits of matter and energy — electrons inside an atom, tiny circuits, massless particles of light — to store, carry and process information.

Dec 23, 2025 · Quantum information is problem solving and data processing using a quantum system as the information carrier, rather than binary ‘1’s and ‘0’s used in conventional computation.

6 days ago · Quantum mechanics and information sciences have been key to many technological advances in the 20th century. They have led to astonishing progress in computing, sensing, and …

Quantum information science aims to explore the nature of information at the quantum level, a world in which bits can be both zero and one at the same time and perfect copying is impossible.

Quantum computing is processing information using sequence of unitary operations (quantum gates) in order to obtain an answer to a prede-termined question, e.g. is a given number factor-izable with …

The development of quantum algorithms and communication protocols, as well as the possibility of implementing them with different systems, has established the field of quantum information as one of …

Quantum information science (QIS) harnesses the laws of quantum mechanics, which govern matter and energy at the atomic and subatomic levels, to store, transmit, manipulate, compute, and …

This course begins with an introduction to the mathematics of quantum information, including a description of quantum information for both single and multiple systems.

The theoretical discovery that quantum information possesses fundamentally distinct properties from classical information has catalyzed a new field exploring the implications of quantum theory on …
