Based on both analytical dipole model analyses and numerical simulations, we
propose a concept of coherent perfect nanoabsorbers (CPNAs) for divergent
beams. This concept makes use of the properties of a slab with negative
refraction and small losses. The proposed CPNA device would allow focusing
radiation in nanoscale regions, and hence could be applied in optical
nanodevices for such diverse purposes as reading the results of quantum
computation which is based on single photon qubits.
