Qulacs-Qibo benchmarks

2

I am contacting you because we would like to understand how the benchmark between Qulacs and Qibo on CPU has been performed in [your paper](https://arxiv.org/abs/2011.13524). Today we rechecked both codes...

The current approach for parallel circuit evaluation uses multiprocessing which seems in conflict with the threading mechanisms of qibojit and qibotf. At the moment this feature is only supported by...

In #352 we observed a performance deterioration. We should reconsider the implementation of a lighter symbol object as a sympy replacement.

From shots to states and expectations

3

We would to have the possibility to convert measurement shots to final state functions and/or to hamiltonian expectation. Some useful techniques are: - Quantum tomography - Quantum Phase Estimation

As discussed, we may consider the possibility to work with hamiltonians defined in a custom numerical representation, for example float32 or float64. This may be useful in cases where an...

The AE and QAOA models may benefit, in terms of memory and performance, from custom operators for ODE solvers.

u280 support

Hi, is it possible to use the current code (`latest`) with the alveo u280? If I understand correctly the overlaybins for this board are not available yet so examples like...
