Sending-or-Not-Sending Twin-Field Quantum Key Distribution with Light Source Monitoring

Sending entanglement through noisy quantum channels.

This paper addresses some general questions of quantum information theory arising from the transmission of quantum entanglement through (possibly noisy) quantum channels. A pure entangled state is prepared of a pair of systems R and Q, after which Q is subjected to a dynamical evolution given by the superoperator $. Two interesting quantities can be defined for this process: the entanglement fi...

Se p 19 98 Sending quantum information with Gaussian states

1 Information characteristics of a quantum channel During the last couple of years an impressive progress has been achieved in the theory of transmission of classical information through quantum communication channels (see [8] for a comprehensive survey). The problem of sending quantum information is much less understood; we refer in particular to the papers [10], [2], [1], initiating the study...

Sending signals dynamically.

Proteins mediate transmission of signals along intercellular and intracellular pathways and between the exterior and the interior of a cell. The dynamic properties of signaling proteins are crucial to their functions. We discuss emerging paradigms for the role of protein dynamics in signaling. A central tenet is that proteins fluctuate among many states on evolutionarily selected energy landsca...

Semantic Email Addressing: Sending Email to People, Not Strings

In this document, we explore how semantic technologies can be brought to email addressing. We introduce the notion of semantic email addressing (SEA). SEA allows emails to be sent to a semantically specified recipient of group of recipients, which may be dynamically changing over time. We give some applications of SEA and describe our prototype imple-
