Phys. Rev. A 70, 062302 (2004) [13 pages]Quantum computing using single photons and the Zeno effectReceived 17 August 2004; published 1 December 2004 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 an alternative paradigm for quantum computation. © 2004 The American Physical Society URL:
