Quantum Distinction: Quantum Distinctiones!
... In (5) we were speaking about self-reference systems and their aggregation in pattern called quantum self-reference system. Now we are going to speak about quantum distinction. We have several reasons or ways to introduce notion quantum distinction, but they nevertheless come to one common reason in ...

Bits more basic for physics than fundamental particles?
... There is at least another trick too, and that is to distinguish between different types of information. Remember that information in the sense of discerning patterns must be said to be subjective, and how might subjectivity — relations with the environment, that particular environment — tie in with ...

... Using quantum-mechanical properties of natural particles, it is possible to build computers that are different in some interesting ways than the ones that we are used to. In our usual computers, a bit is either 0 or 1 at a particular time. As a direct consequence of this, a group (register) of n bit ...

Quantum teleportation
Quantum teleportation is a process by which quantum information (e.g. the exact state of an atom or photon) can be transmitted (exactly, in principle) from one location to another, with the help of classical communication and previously shared quantum entanglement between the sending and receiving location. Because it depends on classical communication, which can proceed no faster than the speed of light, it cannot be used for faster-than-light transport or communication of classical bits. It also cannot be used to make copies of a system, as this violates the no-cloning theorem. While it has proven possible to teleport one or more qubits of information between two (entangled) atoms, this has not yet been achieved between molecules or anything larger.Although the name is inspired by the teleportation commonly used in fiction, there is no relationship outside the name, because quantum teleportation concerns only the transfer of information. Quantum teleportation is not a form of transportation, but of communication; it provides a way of transporting a qubit from one location to another, without having to move a physical particle along with it.The seminal paper first expounding the idea was published by C. H. Bennett, G. Brassard, C. Crépeau, R. Jozsa, A. Peres and W. K. Wootters in 1993. Since then, quantum teleportation was first realized with single photons and later demonstrated with various material systems such as atoms, ions, electrons and superconducting circuits. The record distance for quantum teleportation is 143 km (89 mi).
