QUBIT4MATLAB V3.0: A program package for quantum information science and quantum optics for MATLAB

A program package for MATLAB is introduced that helps calculations in quantum information science and quantum optics. It has commands for the following operations: (i) Reordering the qudits of a quantum register, computing the reduced state of a quantum register. (ii) Defining important quantum states easily. (iii) Formatted input and output for quantum states and operators. (iv) Constructing o...

Quantum Information Science and Complex Quantum Systems

My subject in this paper is using quantum information science as an approach to the study of complex quantum systems. The work I describe has involved many collaborators at the University of Queensland and MIT, but I would especially like to emphasize the contribution of Tobias Osborne. Let me begin by asking what it is that makes quantum information science a science? Friends outside the field...
