  We propose a multi-mode modulation scheme for Continuous Variable (CV)
quantum communications, which we call quantum pattern encoding. In this
setting, classical information can be encoded into multi-mode patterns of
discretely-modulated coherent states, which form instances of a communicable
image space. Communicators can devise arbitrarily complex encoding schemes
which are degenerate and highly non-uniform, such that communication is likened
to the task of pattern recognition. By exploring initial communication schemes
that exploit these techniques, we discuss the impact that this increased
embedding complexity has on the role of a near-term quantum eavesdropper;
formulating new, realistic classes of attacks and secure communication rates.
