cirq.QubitId

class cirq.QubitId

Identifies a qubit. Child classes implement specific types of qubits.

The main criteria that a “qubit id” must satisfy is comparability. Child

classes meet this criteria by implementing the _comparison_key method. For

example, cirq.LineQubit’s _comparison_key method returns self.x. This

ensures that line qubits with the same x are equal, and that line qubits

will be sorted ascending by x. QubitId implements all equality,

comparison, and hashing methods via _comparison_key.
