Many of our Trotter steps are naturally implemented on a linear array. However, many NISQ devices are planar. If one wants to control these linear Trotter steps on an ancilla...

Hubbard model Trotter steps

Eventually it would be great to implement the sqrt(N) depth Trotter steps described in [arXiv:1711.05395](https://arxiv.org/abs/1711.05395) - perhaps @john6060 would be interested in working on this? But more immediately I think...

Now that @Strilanc has setup travis for us we should work on adding more tests! @sunqm @jarrodmcc

Tests for ipython notebooks

We've had a few problems with people submitting pull requests that break the demo file. The demo is quite important because it is likely the first thing that new users...

Increase test coverage to 100%

3

We should aim for 100% test coverage. Coveralls reveals which modules have the least coverage; those with the least coverage, such as molecular_data should be improved first.

Eventually we should include an implementation of these classes in C++ for performance reasons. This should help with faster TimeEvolution calls in ProjectQ, faster transformations, etc.
