  We show that the quantum Zeno effect can be used to suppress the failure
events that would otherwise occur in a linear optics approach to quantum
computing. From a practical viewpoint, that would allow the implementation of
deterministic logic gates without the need for ancilla photons or
high-efficiency detectors. We also show that the photons can behave as if they
were fermions instead of bosons in the presence of a strong Zeno effect, which
leads to a new paradigm for quantum computation.
