# The phfqit package

Utilities to typeset stuff in Quantum Information Theory (quite biased towards theory).

Provides macros to typeset some general mathematical operators (identity operator, trace, diagonal, rank, ...), a powerful implementation of the bra-ket notation (kets, bras, brakets, matrix elements etc. which can be sized as required), delimited expressions such as averages and norms, and some basic Lie algebra/group names. Provides also macros for entropy measures for quantum information theory (smooth min- and max-entropy, smooth relative entropies, etc.).

# Documentation

Run `make sty`

to generate the style file, `make pdf`

to generate the package documentation, and `make install`

to install the package in your local texmf tree. Run 'make' or 'make help' for more info.
