TELECOM COMMUNICATION STRUCTURES

Communication of Complex Data Structures

Communicating complex data structures, that is those containing pointers, across machines is a common problem in distributed and parallel computing ; particularly with the current move towards object-oriented programming. Some techniques utilise dedicated hardware and system software to eeciently achieve this. This paper presents a study of several software techniques for the communication of c...

Message Passing with Communication Structures

Abstraction concepts based on process groups have largely dominated the design and implementation of communication patterns in message passing systems. Although such an approach seems pragmatic—given that participating processes form a ‘group’—in this dissertation, we discuss subtle issues that affect the qualitative and quantitative aspects of this approach. To address these issues, we introdu...

Ultra stable all-fiber telecom-band entangled photon-pair source for turnkey quantum communication applications.

We demonstrate a novel alignment-free all-fiber source for generating telecom-band polarization-entangled photon pairs. Polarization entanglement is created by injecting two relatively delayed, orthogonally polarized pump pulses into a piece of dispersion-shifted fiber, where each one independently engages in four-photon scattering, and then removing any distinguishability between the correlate...
