Quantum machinePhotograph of the quantum machine developed by O'Connell. The mechanical resonator is located to the lower left of the coupling capacitor (small white square). The qubit is connected to upper right of the coupling capacitor. The first quantum machine Cooling to the ground state In order to demonstrate the quantum mechanical behaviour, the team first needed to cool the mechanical resonator until it was in its quantum ground state (the state with the lowest possible energy). Controlling the quantum state In quantum mechanics, vibrations are made up of elementary vibrations called phonons. Notes ^ a: The ground state energy of an oscillator is proportional to its frequency: see quantum harmonic oscillator References External links
