New version program summary Program title: QDensity, QCWave, BTSystem, Circuits Catalogue identifier: ADXH_v4_0 Program summary URL: Program obtainable from: CPC Program Library, Queen's University, Belfast, N. This update will hopefully aid in studies of QC dynamics. Examples of Bell's theorem and concurrence are also included. An overview is given of the new QDensity, QCWave, BTSystem and Circuits packages, which includes: (1) improved treatment of tensor products of states and density matrices, (2) major extension to include qutrit (triplet), as well as qubit (binary) and hybrid qubit/qutrit systems in the associated BTSystem package, (3) updated sample quantum computation algorithms, (4) entanglement studies, including Schmidt decomposition, entropy, mutual information, partial transposition, and calculation of the quantum discord.

The Mathematica quantum computer simulation packages QDENSITY and QCWAVE are updated for Mathematica 9-10.3.
