In a previous paper a proposal for measuring the Husimi Q -function based on the projection synthesis method (Barnett and Pegg 1996 Phys. Rev. Lett. 76 4148) was presented. The scheme required the presence of an unavailable state, named the complementary coherent state. This paper shows how to generate this state in travelling waves and studies its properties.
