Polarization entanglement storage in ensemble-based atomic memories
Quantum networks enable the long-distance communication of quantum states through teleportation, but require, in advance, the robust distribution of entanglement between relevant parties. Engineering these networks requires quantum interconnects, which convert quantum states in one physical system …

Long-distance mother-daughter communication: Identifying changes and maintenance behaviors when daughters leave home
… transitions out of the home and geographical distance is increased between mother and daughter. How a mother and daughter dyad adapt to the changes that happen in their relationship during this transition are crucial to the effectiveness of their adjustment. The current study answers how …

Minimum-delay HF communications
HF radio communications offer latency advantages over fiber-optics and are more economical than satellite links in long-distance communication applications. As a result, there is renewed interest in the field of HF from the high-frequency trading industry, as a means of transmitting financial data. …

Progressively communicating rich telemetry from autonomous underwater vehicles via relays
… until after recovery. Increasing the challenge, long-distance communication may require relaying data across multiple acoustic hops between vehicles, yet fixed infrastructure is not always appropriate or possible. In this thesis I present an analysis of the unique considerations facing telemetry …

Individual contributions to group behaviour in the cooperatively breeding southern ground-hornbill Bucorvus leadbeateri
… The large body size and exceptionally long lifespan of ground-hornbills leads to a “slow” life-history strategy, providing a striking contrast to most wellstudied avian cooperative breeders, which tend to be small, relatively short-lived passerines. Furthermore, while the hornbill …
