Annealing Schedule
Hey,
I had a question regarding annealing schedules in DWAVE 2000Q. Say I start from 0, go to s = 0.5 and then pause at s = 0.5 for 10 micro seconds. After this pause is it possible to do a 10 nano second quench to s = 1.0 (i.e. to finish the anneal)?
I think it is not possible as the gradient in the quench is 50 (while the maximum gradient possible in dwave is 5.00 for annealing).

Hello,
The maximum slope is defined in the documentation here in the last bullet in the list outlining the rules in defining the points of anneal schedules:
https://docs.dwavesys.com/docs/latest/c_solver_parameters.html#anneal-schedule
For the DW_2000Q_6 for example the anneal time range is [ 1, 2000 ].
So the minimum anneal time is 1 microsecond and the maximum slope is 1/(1 microsecond).
You can also plug the solver into the first cell of this Jupyter Notebook and it will give you this information:

The QPU-specific information can also be found by clicking on the QPU name in the Solvers section on the Leap dashboard near the bottom of the page:
