a Labeling of the coordinate systems at the sub-lattices \({\mathcal{A}}\) and \({\mathcal{B}}\). b Typical polymer conformation (10 monomers). The red and dark green dashed lines represent a subset of inter-bead interactions considered in our model. Side chain beads are shown in orange. c Example of turn encoding. d Number of qubits required by the sparse (3-local terms) model (blue) and its dense (5-local terms) variant (orange) as a function of the number of monomers. e Number of Pauli strings with respect to the number of monomers for the sparse and dense encoding models. The parameters of the fit are (a, b) = (0.15, 1.49). The exponential curve (dotted line) is given as a reference.
