Abstract

A scalable, high-performance quantum processor can be implemented using near-resonant dipoledipoleinteracting dopants in a solid state host. In this scheme, the qubits are represented by groundand subradiant states of effective dimers formed by pairs of closely spaced two-level systems, whilethe two-qubit entanglement either relies on the coherent excitation exchange between the dimers oris mediated by external laser fields.
