Spontaneous decay of artificial atoms in a multi-qubit system
Ya. S. Greenberg, A. A. Shtygashev, A. G. Moiseev
We consider a one-dimensional chain of N equidistantly spaced noninteracting qubits embedded in an open waveguide. In the frame of single-excitation subspace, we systematically stu…

Waveguide bandgap N-qubit array with a tunable transparency resonance
Ya. S. Greenberg, A. A. Shtygashev, A. G. Moiseev
We study a single photon transmission through 1D N- qubit chain. The qubits are supposed to be identical with equal distance between neighbors. We express the transfer matrix of N-…

Influence of Impurity on the Rate of Single Photon Superradiance in Disordered N Qubit Chain
Ya. S. Greenberg, A. G. Moiseev
We investigate the rate of superradiant emission for a number of artificial atoms (qubits) embedded in a one-dimensional open waveguide. More specifically, we study the 1D (N+1)- q…
