    "abstract": "As a candidate scheme for controllably coupled qubits, we consider two\nquantum dots, each doped with a single electron. The spin of the electron\ndefines our qubit basis and trion states can be created by using polarized\nlight; we show that the form of the excited trion depends on the state of the\nqubit. By using the Luttinger-Kohn Hamiltonian we calculate the form of these\ntrion states in the presence of light-heavy hole mixing, and show that they can\ninteract through both the F\\\"orster transfer and static dipole-dipole\ninteractions. Finally, we demonstrate that by using chirped laser pulses, it is\npossible to perform a two-qubit gate in this system by adiabatically following\nthe eigenstates as a function of laser detuning. These gates are robust in that\nthey operate with any realistic degree of hole mixing, and for either type of\ntrion-trion coupling.",
