Phys. Rev. Lett. 96, 010503 (2006) [4 pages]Distributed Quantum Computation via Optical FibersReceived 20 July 2005; published 5 January 2006 We investigate the possibility of realizing effective quantum gates between two atoms in distant cavities coupled by an optical fiber. We show that highly reliable swap and entangling gates are achievable. We exactly study the stability of these gates in the presence of imperfections in coupling strengths and interaction times and prove them to be robust. Moreover, we analyze the effect of spontaneous emission and losses and show that such gates are very promising in view of the high level of coherent control currently achievable in optical cavities. © 2006 The American Physical Society URL:
