We show that universal quantum computation can be performed within the ground state of a
topologically ordered quantum system, which is a naturally protected quantum memory. In
particular, we show how this can be achieved using brane-net condensates in 3-colexes.
The universal set of gates is implemented without selective addressing of physical qubits
and, being fully topologically protected, it does not rely on quasiparticle excitations or their
braiding.
