dq.SEPropagatorResult

Result of the Schrödinger equation integration to obtain the propagator.

Attributes

• propagators (array of shape (..., nsave, n, n)) –

  Saved propagators with nsave = ntsave, or nsave = 1 if options.save_states is set to False.

• final_propagator (array of shape (..., n, n)) –

  Saved final propagator.

• extra (PyTree or None) –

  Extra data saved with save_extra() if specified in options (see dq.Options).

• infos (PyTree or None) –

  Solver-dependent information on the resolution.

• tsave (array of shape (ntsave,)) –

  Times for which results were saved.

• solver (Solver) –

  Solver used.

• gradient (Gradient) –

  Gradient used.

• options (Options) –

  Options used.

Result of running multiple simulations concurrently

The resulting propagators are batched according to the leading dimensions of the Hamiltonian H. For example if H has shape (2, 3, n, n), then propagators has shape (2, 3, ntsave, n, n).

See the Batching simulations tutorial for more details.
