Class Documentation

class blackbird::Operation

The base class inherited by all quantum operations. This defines public attributes common to all operations, such as gate name, modes it acts on, number of parameters, number of modes it acts on, as well as parameter details.

It also defines some utility methods for printing out gate information.
