Schmidt-Mode Analysis of Entanglement for Quantum Information Studies
We present examples of the analysis of quantum entanglement entanglement as an introduction to the fundamental basis for quantum computing and information technology. Pure non-separable two-particle states are analysed using the Schmidt decomposition and we introduce the number of effective eigenmodes as a measure of entanglement. We give an elementary illustration, as well as an overview of more complex calculations we have carried out in situations involving bipartite states in continuous Hilbert space.
