Abstract

The ability to coherently store, manipulate, and retrieve quantum information is well known to be crucial to the development of quantum computing, as well as other advanced technologies. A large and coordinated effort within the quantum optics and quantum information community has generated a considerable literature on this subject, and encouraging inroads have been made experimentally. It is desirable to utilize broadband optical links for large-bandwidth quantum communication. Off-resonant interactions allow adiabatic storage of broadband fields, but the coupling is generally weak. The present work shows that an off-resonant quantum memory for ultrafast pulses can in fact be easily optimized to operate deterministically with high efficiency.
