Integrating GPU acceleration support in OpenQuantumTools

2

Just as a first-case test, we implemented a GPU solver as a separate function, https://github.com/USCqserver/OpenQuantumTools.jl/blob/f0e34ec2f94357d9bc1c2fa65459646a8c5b3857/src/QSolver/closed_system_solvers.jl#L30-L44 Ideally, we would integrate better. How we do this is effectively solved by solving the...

Benchmarking time with CPU/GPU solvers for comparison

We've added a GPU solver https://github.com/USCqserver/OpenQuantumTools.jl/blob/f0e34ec2f94357d9bc1c2fa65459646a8c5b3857/src/QSolver/closed_system_solvers.jl#L30-L44 which will get integrated better soon. We've shown informally that for n = 10 qubits and tf = 10ns anneal, the GPU version takes...

Issue when changing phase of 2q operation and passing to `leaky_qubit_model_from_pspec`

3

**Describe the bug** I am building a `leaky_qubit_from_pspec` (see [here](https://github.com/sandialabs/pyGSTi/blob/085f2892656460cfdd19e44701c971db3bbfa100/pygsti/tools/leakage.py#L300)) using the `smq1Q_XYI` model pack, but for technical reasons, I am adjusting the phase on the gate_unitaries inside the model...
