Multi-Field Quantum Conference Key Agreement Using An Integrated Photonic Green Machine, Benjamin J. Fisher

Theses and Dissertations

Quantum Conference Key Agreement (QCKA) enables a group of users to generate a shared secret key, which reduces the latency and equipment overhead of establishing multiple Quantum Key Distribution (QKD) links. Conventional QCKA protocols send a multi-photon entangled state from one user to others and a key is generated only when all photons are detected, which is inefficient at high loss and opens side-channels at the receiver side. Here, we overcome this barrier through a multi-field QCKA protocol enabled by designing, fabricating, and testing an integrated photonic Green Machine that implements an eight-mode Hadamard unitary transformation through a beam-splitter network. …

Exploring Consequences Of The Double Empathy Problem Across The Autistic Trait Spectrum: First Person Accounts, Cammy C. Peck

Theses and Dissertations

Historically, individuals on the autism spectrum were believed to have deficits in empathy. However, recent research suggests that empathy-related issues occur on both sides of the communication dynamic. This concept known as the Double Empathy Problem (DEP), posits that the perceived lack of empathy is not exclusive to autistic individuals; rather, neurotypical (NT) individuals also experience difficulty empathizing with autistic individuals (Milton, 2012). Milton et al. (2022) describes this as a "breakdown in mutual understanding". Such mutual misunderstanding can have adverse consequences for both autistic and neurotypical individuals. To our knowledge, no studies have directly examined these consequences in relation …

Semitic Root Encoding: Tokenization Based On The Templatic Morphology Of Semitic Languages In Nmt, Brendan T. Hatch

Theses and Dissertations

The morphological structure of Semitic languages like Arabic and Hebrew is based on non-concatenative roots and templates. This complex word structure used by humans is obscured to neural models that use traditional tokenization algorithms. In this work, I present and evaluate Semitic Root Encoding (SRE), a tokenization method that represents Semitic words with distinct root and template stem tokens, and apply it to neural machine translation (NMT). I evaluate whether tokenization with the SRE method leads to increases in translation quality, whether it allows NMT models to hypothesize unseen word forms needed at inference, and how impervious resulting NMT models …
