Quantum gates with Quirk

The qubits are represented by the lines, and they start on the left, as shown in following quantum gate programming interface:

Quantum gate programming interface

The gates are logic gates that will transform the state of the qubits:

Not gate:

A not gate will transform a ket-zero |0〉 into a ket-one |1〉. It will transform a ket-one |1〉 into a ket-zero|0〉. 

In circuit description, on is the ket-one state and off is the ket-zero state, as shown in the following quantum score:
