We theoretically examine the capacitive coupling between two quantum dot hybrid qubits, each consisting of three electrons in a double quantum dot, as a function of the energy detuning of the double dot potentials. We show that a shaped detuning pulse can produce a two-qubit maximally entangling operation in ~ 50ns without having to simultaneously change tunnel couplings. Sim- ulations of the entangling operation in the presence of experimentally realistic charge noise yield two-qubit delities over 90%.
