  We propose a practical implementation of a universal quantum computer that
uses local fermionic modes (LFM) rather than qubits. Our design consists of
quantum dots tunnel coupled by a hybrid superconducting island together with a
tunable capacitive coupling between the dots. We show that coherent control of
Cooper pair splitting, elastic cotunneling, and Coulomb interactions allows us
to implement the universal set of quantum gates defined by Bravyi and Kitaev.
Finally, we discuss possible limitations of the device and list necessary
experimental efforts to overcome them.
