Entangling photons via the quantum Zeno effectRalf Schützhold, Andreas Osterloh, and •Nicolai ten Brinke — Fakultät für Physik, Universität Duisburg-Essen, Lotharstraße 1, D-47057 Duisburg, Germany

We present an approach for entangling photons using the quantum Zeno effect and strong two-photon absorption. The quantum Zeno effect describes the suppression of the time evolution of a quantum state by frequent measurements. This effect can be employed for entanglement generation, e.g., to implement a quantum-CNOT gate in a linear optics approach to quantum computing. In contrast to previous proposals, our approach might also work in free space, i.e., without resonators or cavities.
