1. A method of coupling a qubit, said method comprising:
providing a transmission line for at least one of controlling said qubit and reading out a state of said qubit; and
locating said qubit near a transmission line approximately at a location corresponding to a node at a predetermined frequency,
said predetermined frequency comprising a basic operating frequency F01 of said qubit as a frequency difference between a
lowest energy state of said qubit and a second lowest energy state of said qubit.
