Circuit QED Flip-Flop Memory with All-Microwave Switching
Christian Kraglund Andersen, Klaus Mølmer · Physical Review Applied · 2015
One approach to quantum computing seeks to exploit ultralow-power optical pulses working in the few-photon regime. The authors propose an all-microwave flip-flop device, built from superconducting components and controlled by single photon pulses, with memory states driven at the 20-attowatt power level. This device does not rely on metastable atomic states, but instead features memory states with longer lifetimes than those of its individual components.
