  Coupling of transmon qubits to resonators that serve as storage for
information provides alternative routes for quantum computing. Such a scheme
paves the way for achieving high qubit connectivity, which is a great challenge
in cQED systems. Implementations either involve an ancillary transmon's direct
excitation, or virtual photon interactions. Virtual coupling scheme promises
advantages such as the parallel, virtual gate operations and better coherence
properties since the transmon's decoherence effects are suppressed. However,
virtual gates rely on nonuniform frequency separation of the modes in the
system and acquiring this feature is not a straightforward task. Here, we
propose an architecture that incorporates the four-wave mixing capabilities of
the transmon into a chain of resonators coupled collectively by qubits in
between. The system, consisting of numerous resonators all operating within the
single mode approximation, maintains the above-mentioned nonuniformity by
accommodating different resonators with appropriate frequencies.
