    "abstract": "It is considered the indirect inter-qubit coupling in 1D chain of atoms with\nnuclear spins 1/2, which plays role of qubits in the quantum register. This\nchain of the atoms is placed by regular way in easy-axis 3D antiferromagnetic\nthin plate substrate, which is cleaned from the other nuclear spin containing\nisotopes. It is shown that the range of indirect inter-spin coupling may run to\na great number of lattice constants both near critical point of quantum phase\ntransition in antiferromagnet of spin-flop type (control parameter is external\nmagnetic field) and/or near homogeneous antiferromagnetic resonance (control\nparameter is microwave frequency).",
