Dear Mathematica discussion group There is a new version of =93Quantum=94 , the free Mathematica 6 Add-On for Quantum Mechanics and Quantum Computing calculations in Dirac Notation, and plotting of Quantum Circuits. This new version takes into account the suggestions of Francisco Delgado-Cepeda, Jean-Daniel Bancal, Anirban Das, Rub=E9n Dario Santiago-Acosta and Sergio Eduardo Mart=EDnez-Casas, thank you to all of them. You can download Quantum from <http://homepage.cem.itesm.mx/lgomez/quantum/index.htm> http://homepage.cem.itesm.mx/lgomez/quantum/index.htm, there you can also find the installation instructions. Quantum is totally free. Among the new features of =93Quantum=94 for Mathematica 6 we have: Quantum is up to 100 faster in expressions that include many multiplications (thanks to Francisco Delgado) It works with symbolic and infinite sums (thanks to Jean-Daniel Bancal) http://homepage.cem.itesm.mx/lgomez/quantum/sums/sums.html It calculates Partial Transpose (besides Traces, thanks Anirban Das) http://homepage.cem.itesm.mx/lgomez/quantum/tracetranspose/tracetranspose.ht ml It calculates (approx) Exponentials of operators (thanks Ruben Dario) http://homepage.cem.itesm.mx/lgomez/quantum/powerseries/powerseries.html It obtains Dirac expressions from matrices (thanks to Francisco Delgado) http://homepage.cem.itesm.mx/lgomez/quantum/matrices/matrices.html It is possible to specify the order of the qubits when quantum circuits are plotted (thanks to Sergio Mart=EDnez-Casas) http://homepage.cem.itesm.mx/lgomez/quantum/qcircuits/qcircuits.html You can download Quantum from <http://homepage.cem.itesm.mx/lgomez/quantum/index.htm> http://homepage.cem.itesm.mx/lgomez/quantum/index.htm, there you can also find the installation instructions.
