cirq.Gate

class cirq.Gate

An operation type that can be applied to a collection of qubits.

Gates can be applied to qubits by calling their on() method with

the qubits to be applied to supplied, or, alternatively, by simply

calling the gate on the qubits. In other words calling MyGate.on(q1, q2)

to create an Operation on q1 and q2 is equivalent to MyGate(q1,q2).

Gates operate on a certain number of qubits. All implementations of gate

must implement the num_qubits method declaring how many qubits they

act on. The gate feature classes SingleQubitGate and TwoQubitGate

can be used to avoid writing this boilerplate.

Linear combinations of gates can be created by adding gates together and

multiplying them by scalars.
