DecompositionRule

A rule for breaking down specific gates into sequences of simpler gates.

Constructor Summary

Public Constructor
public	constructor(gateClass: function, gateDecomposer: function, gateRecognizer: function)

Name	Type	Attribute	Description
gateClass	function		The type of gate that this rule decomposes. The gate class is redundant information used to make lookups faster when iterating over a circuit and deciding "which rules apply to this gate?" again and again. Note that this parameter is a gate type, not a gate instance. You supply gate_class=MyGate or gate_class=MyGate().class, not gate_class=MyGate().
gateDecomposer	function		Function which, given the command to decompose, applies a sequence of gates corresponding to the high-level function of a gate of type gate_class.
gateRecognizer	function		A predicate that determines if the decomposition applies to the given command (on top of the filtering by gate_class). For example, a decomposition rule may only to apply rotation gates that rotate by a specific angle. If no gate_recognizer is given, the decomposition applies to all gates matching the gate_class.
