Abstract (in Japanese) (See Japanese page) 
(in English) Exciton-polaritons are bosonic quasi-particles originating from the strong coupling of a cavity photon and a quantum well exciton in semiconductor microcavities. Recently it has become clear that exciton-polaritons undergo Bose-Einstein condensation (BEC) and have opened up new possibilities for exploring fundamental quantum states of matter such as superfluidity , and quantized vortex formation on a semiconductor chip. Exciton-polariton condensates emit coherent light via photoluminescence through the microcavity mirrors due to the spontaneous formation of coherence. Unlike conventional lasers which emit coherent Gaussian light, polaritons possess a natural nonlinearity due to the interaction of the excitonic component. We show that by using suitable phase fixing methods it is possible to take advantage of this to produce light with a negative component to the Wigner function at steady-state operation. In contrast to many other proposals for sources of non-Gaussian light, in our case, the light typically has an average photon number exceeding one and emerges as a continuous wave. The light emerges entirely deterministically without the need of measurement. Such a source may have uses in continuous-variable quantum information and communication.
