A paper “Qubit lattice coherence induced by electromagnetic pulses in superconducting metamaterials” by researches of our laboratory Zoran Ivic, Nikolaos Lazarides and Georgios Tsironis published in a journal Scientific Reports that is a part of Nature group. The article is available in web page Publications. A superconducting quantum metamaterial comprising superconducting charge qubits loaded periodically on a superconducting transmission line has been investigated theoretically and numerically. In the paper it is demonstrated that two remarkable quantum coherent optical phenomena, i.e., self-induced transparency and Dicke-type
superradiance, may occur during light-pulse propagation in this quantum metamaterial. Also it is demonstrated that the propagating electromagnetic pulses may induce quantum coherent population inversion pulses in the metamaterial.
Our colleagues believe that the experimental confirmation of such effects in superconducting quantum metamaterials may open a new pathway to potentially powerful quantum computing.
