Practical and reliable error bars for quantum process tomography

1 code implementation1 Aug 2018 Le Phuc Thinh, Phillippe Faist, Jonas Helsen, David Elkouss, Stephanie Wehner

We also provide a software package---QPtomographer---implementing our estimator for the diamond norm and the worst-case entanglement fidelity.

How to transform graph states using single-qubit operations: computational complexity and algorithms

1 code implementation14 May 2018 Axel Dahlberg, Jonas Helsen, Stephanie Wehner

Here the runtime is O(poly(|V(G)|)), showing that more efficient algorithms can in principle be found even for states holding a large amount of entanglement, as long as the output state has constant size.
