Quantum information is a new forefront inter-discipline which combines information science with quantum physics. It has the unique characteristics of entanglement and non-localized connection with which the classical information science can抰 compare. This poses a new problem to philosophy. On the basis of the foundation of information theory by science and technology, the article redefines information from the philosophical angle, thinking information is an objective existence in the form of non-substance with movement as its presentation. The article explains the three kinds of intrinsic unitarity of quantum information: the unitarity between information existence and quantum existence, the unitarity between determinism and non-determinism, the unitarity between locality and non-locality.Quantum information is a new forefront inter-discipline which combines information science with quantum physics.

What is the speed of quantum information?

Robert Garisto

We study the apparent nonlocality of quantum mechanics as a transport problem. If space is a physical entity through which quantum information (QI) must be transported, then one can define its speed. If not, QI exists apart from space, making space in some sense `nonphysical'. But we can still assign a `speed' of QI to such models based on their properties. In both cases, classical information must still travel at $c$ , though in the latter case the origin of local spacetime itself is a puzzle. We consider the properties of different regimes for this speed of QI, and relevant quantum interpretations. For example, we show that the Many Worlds Interpretation (MWI) is nonlocal because it is what we call `spatially complete'.We study the apparent nonlocality of quantum mechanics as a transport problem.

Quantum information

Guolin Wu

Quantum information stands apart from classical information, rooted in the principles of quantum mechanics and quantum information theory. Quantum states serve as the fundamental unit of quantum information, whose evolution is governed by the laws of quantum mechanics. While some philosophers, such as A. Duwell have argued that there is no quantum information, which is not a new concept and can be described using Shannon information theory, others, like C. M. Caves and C. A. Fuchs have proposed that quantum information represents classical information stored within quantum systems. However, this chapter argues that quantum information exists and is different from classical information from the perspectives of how information exists and how it is transmitted. Quantum information, unlike classical information, can be categorized into two kinds: Ontological quantum information and epistemological quantum information, where the former reflects the inherent state of microscopic particles, which is independent of observation, and the latter describes how we perceive their state through measurements. Finally, this chapter explores the connection between quantum information and quantum reality. Quantum reality refers to the show of the self-identity of quantum entities. Quantum information, on the other hand, is the show of the states and correlative ways of quantum entities, and it coexists with quantum reality.Quantum information stands apart from classical information, rooted in the principles of quantum mechanics and quantum information theory.
