Software-compatible framework for partitioning CVQC computations

Develop a theoretical, software-compatible framework that partitions continuous-variable quantum computations (CVQC) into inhomogeneous components, enabling the application of efficient optimization routines, approximations, or numerical methods to each component.

Background

The paper highlights that current CVQC simulation tools are fragmented and largely limited to three special cases: Gaussian processes, Fock-space truncations, and boson sampling. These limitations hinder unified software design and broader expressibility for CVQC.

In response, the authors introduce a new graphical calculus intended to unify continuous and Fock-space representations. Within this broader vision, they explicitly pose the need for a general framework that decomposes CVQC computations into parts amenable to efficient classical techniques, making this an identified open question in the field.
