  We introduce quantum circuits for simulations of multi-mode state-vectors on
3D cQED processors, using matrix product state representations. The circuits
are demonstrated as applied to simulations of molecular docking based on
holographic Gaussian boson sampling, as illustrated for binding of a
thiol-containing aryl sulfonamide ligand to the tumor necrosis factor-$\alpha$
converting enzyme receptor. We show that cQED devices with a modest number of
modes could be employed to simulate multimode systems by re-purposing working
modes through measurement and re-initialization. We anticipate a wide range of
GBS applications could be implemented on compact 3D cQED processors
analogously, using the holographic approach. Simulations on qubit-based quantum
computers could be implemented analogously, using circuits that represent
continuous variables in terms of truncated expansions of Fock states.
