> Title: Non-holonomic tomography and detecting state-preparation and
> measurement correlated errors
>
> Abstract: Quantum tomography is an important tool for characterizing the
> parameters of unknown states, measurements, and gates.  Standard quantum
> tomography is the practice of estimating these parameters with known
> measurements, states, or both, respectively.  In recent years, it has
> become important to address the issue of working with systems where the
> ``devices'' used to prepare states and make measurements *both *have
> significant errors.  Of particular concern to me is whether such
> state-preparation and measurement errors are correlated with each other.
> In this talk, I will share a solution to assessing such correlations with
> an object called a partial determinant.  Further, I will show how this
> technique suggests a perspective for such correlated quantum states and
> observables (over the space of device settings) is analogous to the
> non-holonomic perspectives of thermodynamic heat and work (over the
> macroscopic state space.)
