__analytical__–

__not numerical__(matrix) entry of bra-ket convertion – operations on bra-ket, in particular – tensor product ?

For example – how

__in analytical__form to do this:

**U**[itex]|\Psi\rangle[/itex]

where:

**U**=

**I**[itex]\otimes[/itex]

**I**

**I**=[itex]|0\rangle\langle0|+|1\rangle\langle1|[/itex]

[itex]\Psi=\frac{1}{\sqrt{2}}\left( {|0\rangle\otimes|0\rangle+|1\rangle\otimes|1 \rangle} \right)[/itex]

Also – is it possible to do it in the

__analytical__(

__not numerical__) form in the package “Wolfram Mathematica” ? [itex] [/itex]
