Estimating Bell Diagonal states with separable measurements
Noah Kaufmann, Maria Quadeer, David Elkouss
Quantum network protocols depend on the availability of shared entanglement. Given that entanglement generation and distribution are affected by noise, characterization of the shar…

Haar-random and pretty good measurements for Bayesian state estimation
Maria Quadeer
We study Haar-random bases and pretty good measurement for Bayesian state estimation. Given Haar-random bases we derive a bound on fidelity averaged over IID sequences of such…
