abstract = {Left-Handed transmission lines can be designed to exhibit
many modes near the typical transmon frequency. This
multiplicity can be used to enhance qubit-qubit coupling, as
opposed to just a single mode. We demonstrate that the
strength of coupling between the transmon and the
metamaterial modes depends on the qubit's frequency and its
relative position with respect to the transmission line in a
nontrivial manner, setting it apart from coupling via
conventional (right-handed) transmission lines. Through
simulations involving two transmons placed at different
positions and operating at various flux-tuned frequencies,
we can intentionally manipulate the coupling strength
between the transmon and the resonator modes. Consequently,
we study effective qubit-qubit interaction and its
interesting features, which offer a high degree of
flexibility in designing the desired interactions between
the qubits, which can be activated or deactivated by making
slight adjustments to the transmon frequency, typically
within a range of just tens of megahertz.},
