Hi,
I carried out a test to compare the results of Conformational Sampling between versions 2.12 and 3.01 of CREST. In this test, the calculation is performed sequentially on models of linear alkan…

# Abstract
Aqua has a DOcplex translator for optimization problems. It automatically generate an Ising Hamiltonian for an optimization problem from an optimization model to solve it with quantum co…

I used the following code for demonstrating the 4-fold degeneracy of toric code model, without success. I leave an issue here so that someone (including me) could inspect it in the future.

In the Hamiltonian MCMC [notebook](https://github.com/pints-team/pints/blob/master/examples/sampling/hamiltonian-mcmc.ipynb) is at the very bottom the number of divergent transitions displayed.
In…

Now we support `expval` of a sparse Hamiltonian (with Kokkos), but not for the adjoint differentiation method.
On the other hand, `expval` of a Hamiltonian involving `Hermitian` is not supported in…

now sure why yet, when creating hamiltonian matrix for 8x8 graph
```julia
julia> H = @time SparseMatrixCSC(h, space)
ERROR: ArgumentError: row indices I[k] must satisfy 1

Hi,
After running some SHARC/RICC2 simulations with ADC(2) using spin-orbit coupling, I noticed that the Hamiltonian listed in QM.out/output.dat is entirely real. This is opposed to e.g. CASSCF cal…

The goal is to replace GRAPE with GRAFS. This issue creates a dummy function which could be dropped in place of GRAPE. This function takes the same input types and returns and output of the same type …

Dear Zhong Yang
When I tried to run HamGNN in the GPU platform, I encountered some problem due to the version of the python library. However, the library that I have installed is completely in accord…

# Abstract
The problem of Hamiltonian simulation can be described as, given a hermitian matrix H and a real number t, find a circuit for exp(iHt).
Usually this is a hard problem and a widely used …
