ytterbium

Kilian W. Kluge

ytterbium is a Python package built on QuTiP to simulate optical transitions in 171Yb+ and 174Yb+ ions by solving Lindblad form master equations.

In addition to various models of commonly encountered experimental situations, ytterbium contains a small library for parallelized computations which provides a significant speedup when a system needs to be solved for many different parameter values (parallelize).

Requirements

To run ytterbium, the General Requirements for running QuTiP need to be fulfilled and qutip needs to be installed.

The Clebsch-Gordan calculator, which is not required for normal use, additionally requires sympy.

While it is possible to run qutip on Python 2.7.x, ytterbium is developed on Python 3.6 and will not work correctly on Python <3.6 without modifications.

Getting Started

If you are familiar with the basics of qutip, we recommend to have a look at simulations.examples.lineshape to see both how the models in ytterbium are designed and how parallel evaluation can be used to speed up calculations.

If you have never worked with qutip or master equations before, we suggest you first read the excellent introduction to the Lindblad Master Equation Solver in the qutip documentation. Then, we recommend starting with the two-level model of the S-P transition in 174Yb+ (Yb174.twolevel) and the corresponding tests (test.Yb174.test_twolevel).
