Paper Abstract

As computer processing and memory elements continue to shrink in size, quantum effects will no longer be negligible. This is especially important for memories, since these are expected to reach quantum size limits first. For example, if current trends continue, magnetic memory domains will become so small that the energy required to flip the domain orientation will become comparable to the Boltzmann energy, kT, at room temperature. To address these issues, the field of quantum computing has undergone substantial recent growth. However, quantum computers will require quantum memories and while many potential quantum computer designs are being explored, relatively few quantum memories are being developed. With this in mind, the prospects for storing quantum information in rare earth doped crystals are explored. In particular, the promising ultra-slow and stopped light storage schemes are described in detail, and projections are made based on experimental results.
