Quantum computer with dipole-dipole interacting two-level systems
David Petrosyan, Gershon Kurizki · Quantum Information and Computation · 2006
A scalable, high-performance quantum processor can be implemented using near-resonant dipole-dipole interacting dopants in a transparent solid state host. In this scheme, the qubits are represented by ground and subradiant states of effective dimers formed by pairs of closely spaced two-level systems, while the two-qubit entanglement either relies on the coherent excitation exchange between the dimers or is mediated by external laser fields.
