Abstract
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.
