Scalable solid-state quantum processor using subradiant two-atom states
arXiv:quant-ph/0205174 · doi:10.1103/PhysRevLett.89.207902
Abstract
We propose a realization of a scalable, high-performance quantum processor whose qubits are represented by the ground and subradiant states of effective dimers formed by pairs of two-level systems coupled by resonant dipole-dipole interaction. The dimers are implanted in low-temperature solid host material at controllable nanoscale separations. The two-qubit entanglement either relies on the coherent excitation exchange between the dimers or is mediated by external laser fields.
