Strong Coupling Cavity Quantum Electrodynamics ultra
Climbing the Jaynes-Cummings Ladder • Why climb the ladder? – In principle first doublet can be interpreted classically – Sqrt(n) is a pure quantum effect • provides direct evidence for field quantization • studied in time-resolved measurements of ‘the atom’ – No spectroscopic observation of the photons so far • How climb the ladder? – Cool cavity and qubit to ground state – Controllably increase # of excitations in the system • Thermal photons (elevated temperatures) • Multi photon processes (high probe powers) • Pump and probe spectroscopy • We demonstrate in a pump and probe experiment J.
