Efficient Constructions of Streaming Codes
Streaming codes are a class of erasure codes that operate on a stream of packets and enable recovery of dropped or erased packets under a decoding-delay constraint. The primary focus of this thesis is on providing constructions ...
Capacity Computation and Coding for Input-Constrained Channels
The setting of the transmission of information over noisy, binary-input, memoryless channels is today well-understood, owing to the work of several information theorists, beginning with Claude Shannon. It is known that it ...
Coding Schemes for Secure and Reliable DNA-Based Data Storage
In DNA-based data storage, the desired information is encoded into the quaternary
sequence of synthetic DNA molecules, called oligos. We look at secure communication
via information-containing oligos in the usual three-party ...
Opacity and its Trade-offs with Security in Linear Dynamical Systems
Opacity is notion of privacy that is well-studied in computer science and discrete-event systems. In our work, we extend the opacity notion to linear dynamical systems. Opacity describes an eavesdropper’s inability to ...
Tailoring Van – der – Waal materials for nonlinear nanophotonics
Van der Waals or two-dimensional (2D) material are emerging nanomaterials which has shown tremendous potential in building next-generation nonlinear optical devices. Monolayer and multilayer 2D materials exhibit strong ...
Resonant Metasurfaces for Mid-Infrared Photonics
The field of photonics offers a robust platform for efficient light-based technologies,
directly impacting or serving as competent alternatives to address scientific problems. With the
advent and advancement of micro-nano ...
Index Coding over Noisy Channels and Some Applications
A broadcast channel that is very effective for disseminating common content becomes highly inefficient when the users request different content. To address this inefficiency of the broadcast channel over which a server ...
Performance Analysis of Orthogonal Time Frequency Space Modulation in High-Doppler Channels
Next generation wireless systems are envisioned to offer dependable and consistent user experience across a wide range of environments, including high-mobility scenarios involving high-speed trains, aircrafts, and ...
High Dimensional Quantum Information Technology Using Photonics: Protocol Development and Implementation Schemes
This thesis explores the realm of high-dimensional quantum information processing through the lens of photonics, focusing on developing and implementing quantum technologies based on d-level quantum systems known as qudits. ...
Excitonic complexes in semiconducting monolayers and their twisted heterojunctions
Monolayers of transition metal dichalcogenides (TMDCs) host excitons, a bound state of
electron and hole. Excitonic many-body complexes dominate the optical spectra obtained
from this system and manipulating these complexes ...
