Quantum Information Theory

Shai Machnes

Developing intuition about quantum information theory problems is difficult, as is verifying or ruling-out of hypothesis. We present a Matlab package intended to provide the QIT community with a new and powerful tool-set for quantum information theory calculations. The package covers most of the "QI textbook" and includes novel parametrization of quantum objects and a robust optimization mechanism. New ways of re-examining well-known results is demonstrated. QLib is designed to be further developed and enhanced by the community and is available for download at www.qlib.info

In this presentation we expand on the topics discussed in the presentation with the same title (Part I): the Quantum Information viewpoint on Biological systems and what life is, with implications to different areas of study and practices, including alternative medicine, music as an approach to healing etc. The new paradigm in science, brought by progress in the Theory of Quantum Information, can by encoded in the symbolic equation “QI=qi”, i.e. quantum information is chi/qi. The presentation is not meant to be technical, but rather informative, providing “food for thought”.

Numerical investigations are an important research tool in quantum information theory. There already exists a wide range of computational tools implemented in various programming languages. However there is little effort in implementing this kind of tools in the Julia language. Julia is a modern numerical computation library with excellent support for vector and matrix algebra, extended type system that allows for implementation of elegant application interfaces and support for parallel and distributed computing. QI.jl is a new quantum information theory library implemented in Julia that provides functions for creating and analyzing quantum states, and for creating quantum operations in various representations. An additional feature of the library is a collection of functions for sampling random quantum states and operations such as unitary operations and generic quantum channels.
