Quantum information processing by nuclear magnetic resonance
... Information, however it may be conceived, exists only by virtue of being stored in the state of some physical system. The physics of its embodiment, in turn, determines what can be done with the information.17 Quantum information processing is the study of the encoding, transmission, and dynamics of ...

An Extreme form of Superactivation for Quantum Zero-Error
... In order to prove our results, we need some basic notions from algebraic geometry (see e.g. Ref. [7]). A key concept is that of a Zariski-closed set, and the resulting Zariski topology. We will only ever work over base fields C or R, so for our purposes Zariski-closed sets are sets defined by a coll ...
