### Summary `grid_map` is mapping utility for mapping a function over a "grid" of argument values. E.g. for two arrays `a` and `b`, ``` grid_map(f, a, b)[i, j] = f(a[i],...
### Informations - **Qiskit Dynamics version**: `0.4.2` - **Python version**: `3.11.7` - **Operating system**: `Ubuntu 22.04.3 LTS` ### What is the current behavior? The call to `DynamicsBackend.from_backend` throws a `ValueError`...
### What is the expected behavior? Currently the `solve_lmde_perturbation` function requires that the labels for the perturbations be non-negative integers. It would be nice to allow more general labels, e.g....
### Information - **Qiskit Dynamics version**: `main` - **Python version**: `3.10` - **Operating system**: `linux` ### What is the current behavior? 1. Instantiating a `DynamicsBackend` using `DynamicsBackend.from_backend` has an incorrect...
In https://qiskit.org/ecosystem/dynamics/tutorials/Rabi_oscillations.html the relationship between the `hamiltonian_operators`, the `signals` passed to the solver and the time-dependent term in the Hamiltonian isn't explicitly stated. I think readers who are not familiar...
### What is the expected behavior? The simulation of pulse schedules are much slower with `DynamicsBackend.run` method than with `Solver.solve` method when the simulation is done with Jax. It was...
# Summary Make the fixed step solvers compileable/differentiable with respect to the `t_span` and `t_eval` arguments. This isn't an extremely urgent issue, however it would still be very nice to...
### What is the expected behavior? Add a function (or enhance an existing one) to `RotatingFrame` that is `qiskit.quantum_info` "type aware", to be used at a higher level so that...
### What is the expected behavior? Currently, if a `Solver` is instantiated with Lindblad data, calling `Solver.solve` with `y0` being a `SuperOp` will only work if `evaluation_mode` is set to...
### What is the expected behavior? When a parallel solver is used, the solver attempts to parallelize over every single time step that is being solved. As a result, these...
