- tenpy.simulations.measurement.measurement_index(results, psi, simulation, key='measurement_index')[source]¶
‘Measure’ the index of how many mearuements have been performed so far.
The parameter description below also documents the common interface of all measurement functions, that can be registered to simulations.
- Parameters
results (dict) – A dictionary with measurement results performed so far. Instead of returning the result, the output should be written into this dictionary under an appropriate key (or multiple keys, if applicable).
psi – Tensor network state to be measured. Shorthand for
simulation.psi
.simulation (
Simulation
) – The simulation class. This gives also access to the model, algorithm engine, etc.key (str) – (Optional.) The key under which to save in results.
**kwargs – Other optional keyword arguments for individual measurement functions. Those are documented inside each measurement function.
