sites

Method of OperatorNamed.

sites() -> List​

Returns the sites of a named operator in definition order. Unlike support(), this preserves the order of sites as they appear in the operator definition. Important: The order returned is the constructor order, not necessarily the order of mathematical application.

Returns​

A list of indices representing the qubits the operator acts on, in the order they were specified in the constructor.

Example​

var op1 = X(0)
var sites1 = sites(op1)  // Returns [0]
var op2 = XX(0, 1)
var sites2 = sites(op2)  // Returns [0, 1]
