Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels.
An unknown quantum state \ensuremath{\Vert}\ensuremath{\varphi}〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-RosenExpand

Mixed-state entanglement and quantum error correction.
Entanglement purification protocols (EPPs) and quantum error-correcting codes (QECCs) provide two ways of protecting quantum states from interaction with the environment. In an EPP, perfectlyExpand

Purification of noisy entanglement and faithful teleportation via noisy channels.
Two separated observers, by applying local operations to a supply of not-too-impure entangled states ({\em e.g.} singlets shared through a noisy channel), can prepare a smaller number of entangledExpand

Optimal detection of quantum information.
Two quantum systems are identically prepared in different locations. An observer's task is to determine their state. A simple example shows that a pair of measurements of the von Neumann type is lessExpand

Classical information capacity of a quantum channel.
We consider the transmission of classical information over a quantum channel. The channel is defined by an ``alphabet'' of quantum states, e.g., certain photon polarizations, together with aExpand

Limitation on the amount of accessible information in a quantum channel.
We prove a new result limiting the amount of accessible information in a quantum channel. This generalizes Kholevo{close_quote}s theorem and implies it as a simple corollary. Our proof uses theExpand

Spatially Extended Avalanches in a Hysteretic Capillary Condensation System: Superfluid 4He in Nuclepore.
Capacitive studies of hysteretic capillary condensation of superfluid {sup 4}He in Nuclepore have shown that the initial draining of the pores occurs over a small range of the chemical potential withExpand
