Correspondence of Bell State and One-Particle State Transformations

Abstract

There is a direct correspondence between two-particle, entangled quantum states, for example, Bell states, and the relative values of the component one-particle states. This leads to a new rationale for quantum computing which makes use of sequential processing of one-particle states rather than the parallel processing associated with multiparticle states. It is shown that deterministic transformations can correspond to certain Bell state operations. There are some implications for the continuing discussion of quantum realism and entanglement. A principle of relative realism is advocated.
