1. In the present article we address the question 'What is quantum information?' from a conceptual viewpoint.
2. In particular, we argue that there seems to be no sufficiently good reasons to accept that quantum information is qualitatively different from classical information.
3. Quantum information is information stored in very small structures called qubits.
4. The 2012 Nobel Prize in Physics was awarded to two physicists for fundamental discoveries in quantum information.
5. Breakthroughs at NIST enabled the first forays into real-world quantum computing and tested the limits of quantum information and security.
6. For the generic situation in quantum information theory, an irreducible Weyl system is represented on the Hilbert space describing a system of several single particles.
7. In recent years, however, research into the very foundations of quantum mechanics has also led to a new field – quantum information technology.
8. The really novel feature of quantum information technology is that a quantum system can be in a superposition of different states.
9. Furthermore, it is desirable to have states that have reasonably long lifetimes (on the scale of the experiment) so that the quantum information is not lost to the environment through decoherence.
10. The fact that quantum uncertainty comes into play in quantum information might seem to imply a loss of information.
11. Quantum information refers to both the technical definition in terms of Von Neumann entropy and the general computational term.
12. Just like the basic unit of classical information is the bit, quantum information deals with qubits.
13. Quantum information can be measured using Von Neumann entropy.
14. Extracting and manipulating information stored in individual atoms naturally started to become an interesting avenue, and quantum information and computation was starting to get developed.
15. The National Science Foundation can and should play the leading role in addressing these problems and in fostering the continued success of quantum information science.
16. The emerging discipline of quantum information science (QIS) is providing profound new insights into fundamental problems relating to both computation and physical science.
17. The explosive recent development of quantum information science can be attributed to two essential converging factors.
18. Indeed, quantum information can be exploited to perform tasks that would be impossible or very difficult in a classical world.
19. Quantum information systems hold out the possibility of extremely secure encryption—a major attraction in an age where cybersecurity is constantly at risk.
20. Quantum information is the effort to both understand and use the properties of the quantum world.
21. The information stored in such a computer would be quantum information, composed of qubits (short for "quantum bit") instead of bits.
22. One major focus of quantum information researchers at Perimeter is to understand the properties of quantum information.
23. Sometimes this takes the form of figuring out what new technologies quantum information can enable (such as new quantum cryptography protocols).
24. In quantum mechanics, quantum information is physical information that is held in the "state" of a quantum system.
25. The ability to manipulate quantum information enables us to perform tasks that would be unachievable in a classical context, such as unconditionally secure transmission of information.
26. Quantum information processing is the most general field that is concerned with quantum information.
27. Quantum information, and changes in quantum information, can be quantitatively measured by using an analogue of Shannon entropy.
28. 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.
29. At the practical level, quantum information powers forms of secure communication that are provably impossible in a “classical” world.
30. Quantum information researchers at SITP have played an important role in the development of the basic theory of quantum communication.
31. It is also suitable for students learning quantum information theory … .
32. Quantum information science involves the exploration and exploitation of features which rely on the quantum mechanical nature of reality.
33. The realization of a large quantum information processor could enable secure communication and quantum simulation of complex physical systems.
34. Active research at the UW includes work focused on new materials and possible physical realizations of multi-qubit processors as well as on theoretical aspects of quantum information.
35. Quantum information systems can use the probability that a qubit will be in one state or the other when measured to make calculations.
36. This course on quantum information science is a collective effort to further advance knowledge and understanding in quantum information and quantum computing.
37. Our researchers pursue a range of projects in materials for quantum information, quantum computing, and quantum sensing.
38. To make this a reality, the alliance will advance quantum information systems using several hardware approaches, including superconducting, trapped ion, and trapped atom quantum bits (or qubits).
39. “By developing and applying programmable quantum information systems, we hope to define a new frontier at the cutting edge of science and engineering.

41. This course builds quantum information theory from the ground up, connecting it to classical informaiton theory at each step of the way.
42. Research that supports quantum computing, simulation, communication, and sensing is at the core of PNNL’s quantum information science (QIS) strategy.
43. Welcome to Quantiki, the world's leading portal for everyone involved in quantum information science.
