Abstract: We review the theoretical aspects of pseudo-spin quantum computation using vertically coupled quantum dots in the quantum Hall regime. We discuss the robustness and addressability of these collective, charge-based qubits. The low-energy Hilbert space of a coupled set of qubits yields an effective quantum Ising model tunable through external gates. An experimental prediction of an even–odd effect in the Coulomb-blockade spectra of the coupled quantum dot system allows for a probe of the parameter regime necessary for realization of these qubits.
