Abstract
By attributing a circulating Josephson current induced diamagnetic moment to a SQUID-type three-level qubit, a wireless connection between such qubits is proposed based only on dipole-dipole interaction between their moments. The estimates of the model parameters suggest quite an optimistic possibility to experimentally realize the suggested coupling scheme.
