Optical nonlinearities usually occur at large intensities, but discrete transitions allow for giant nonlinearities operating at the single-photon level. Here, the authors demonstrate a two-mode giant nonlinearity with a single semiconductor quantum dot, embedded in a broadband photonic wire antenna. They exploit two detuned optical transitions associated with the exciton-biexciton quantum-dot level scheme. The reflection of one laser beam is controlled by the other beam with a threshold power as low as ten photons per exciton lifetime (1.6 nW). Such a two-color nonlinearity opens up appealing perspectives for the realization of integrated ultralow-power logical gates and optical quantum gates.

Frustrated spin systems prevent the formation of conventional magnetic order and can form an entangled spin state. A frustrated square lattice with only nearest-neighbor interactions is called a fully frustrated square lattice (FFSL) and expected to exhibit strong quantum fluctuations. Here, the authors present an experimental realization of an =½ FFSL composed of a verdazyl-based salt. calculations indicate the formation of an FFSL with competing ferro- and antiferromagnetic nearest-neighbor interactions. The magnetic behavior demonstrates that the system forms a quantum valence-bond solid state. This material provides a way to realize a variety of =½ FFSLs through the molecular design method, proposed here.
