Abstract

The linear optics approach to quantum computing has several potential advantages, but the logic operations are probabilistic. We review the use of the quantum Zeno effect to suppress the intrinsic failure events in these kinds of devices, which would produce deterministic logic operations without the need for ancilla photons or high-efficiency detectors. The potential advantages of implementing Zeno gates using microcavities and electromagnetically induced transparency are discussed.
