The Walrus Documentation¶
A library for the calculation of hafnians, Hermite polynomials, and Gaussian boson sampling.
Fast calculation of hafnians, loop hafnians, and torontonians of general and certain structured matrices.
An easy to use interface to use the loop hafnian for Gaussian quantum state calculations.
Sampling algorithms for hafnian and torontonians of graphs.
Efficient classical methods for approximating the hafnian of non-negative matrices.
Easy to use implementations of the multidimensional Hermite polynomials, which can also be used to calculate hafnians of all reductions of a given matrix.
To get the The Walrus installed and running on your system, begin at the download and installation guide. Then, familiarise yourself with some background information on the Hafnian and the computational algorithm.
For getting started with using the The Walrus in your own code, have a look at the Python tutorial.
Finally, detailed documentation on the code and API is provided.
