Teleportation Protocols Requiring Only One Classical Bit
Subhash Kak
The standard protocol for teleportation of a quantum state requires an entangled pair of particles and the use of two classical bits of information. Here, we present two protocols…
Bell States, Dense Coding, and Teleportation
Subhash Kak
The question of the measurements on the Bell states by making use of mode change (from mixed to pure) of one qubit is considered. Such a mode change cannot be taken advantage of fo…
Paradox of Quantum Information
Subhash Kak
The notion of quantum information related to the two different perspectives of the global and local states is examined. There is circularity in the definition of quantum informatio…
Representation of Entangled States
Subhash Kak
Associating a physical process with the pure entangled state 1/sqrt 2 (|00> + |11>) is an idealization unless the pair is so prepared using an appropriate quantum gate operating on…
