Extends adaptive Bayesian quantum tomography as described in https://doi.org/10.1103/PhysRevA.85.052120 by using a hierarchical distribution over density matrices of all possible ranks. Includes: a Haskell library a shared library which provides a C interface to the tomography function an executable that simulates tomography of random states and outputs infidelity between true states and mean Bayesian estimates to a file Please refer to HABQT-simulation --help for executable usage instructions, README on Github for installation instructions and shared library C ABI description, accompanying Haddock documentation for Haskell API.
