Lloyd modelled the object as a beam splitter with a reflectivity of zero when meTamaTerials the object was not there and a small but non- an added dimension zero reflectivity when the object was there. Expressions for the probability of To fulfil their potential, metamaterials detecting a photon were devised for both need a magnetic component. Incident high- and low-noise regimes. In the low- light can excite a current that circulates noise regime, detection of a single photon each unit cell, such as a split-ring is sufficient to confirm that the object is resonator or a cut-wire pair. This forms present. In the high-noise regime, enough a close analogy to the orbital current signal photons must be sent so that the in atoms. Na Liu and co-workers have probability distribution for detected photons now studied the interplay between these that are all noise can be distinguished from ‘magnetic atoms’ in a stacked layer, the probability distribution for both noise forming the metamaterial equivalent of and reflected signal photons. ley molecules — magnetic molecules.
