Non-destructive electron microscopy through interaction-free quantum measurement
… this thesis, the possibility of interaction-free quantum measurements with electrons is investigated. With a scheme based on existing charged particle trapping techniques, it is demonstrated that such interaction-free measurements are possible in the presence of previously measured quantum …

Value Indefiniteness, Randomness and Unpredictability in Quantum Foundations
The outcomes of quantum measurements are generally considered to be random, but despite the fact that this randomness is an important element in quantum information theory, its nature is not well understood. In this thesis, we study several issues relating to the origin and certification of quantum …

Quantum State Discrimination with Overcompleteness
… for binary hypothesis testing in classical and quantum settings and overcomplete quantum measurements for quantum binary state discrimination. With this we explore decision and measurement operating characteristics defined as the tradeoff between probability of detection and probability of false …

Quantum signal processing
Quantum signal processing (QSP) as formulated in this thesis, borrows from the formalism and principles of quantum mechanics and some of its interesting axioms and constraints, leading to a novel paradigm for signal processing with applications in areas ranging from frame theory, quantization and …

Coherent control of electron spins in diamond for quantum information science and quantum sensing
… electron spins in diamond for applications in quantum information processing and quantum sensing. Specifically, optically-detected magnetic resonance measurements are performed on quantum states of single and multiple electronic spins associated with nitrogen-vacancy centers and other …

Applications of quantum measurement techniques: counterfactual quantum computation, spin hall effect of light, and atomic-vapor-based photon detectors
… phenomena in atomic and optical physics, and quantum information science, by utilizing various types and techniques of quantum measurements. It is the deeper concepts of these measurements, and the way they are integrated into the seemingly unrelated topics investigated, which binds together …

Aspects of Quantum Coherence
… our aim is to study several aspects related to quantum coherence as understood to correspond with the non-classical behaviour that can be observed for certain particular states of a physical system. In particular we are interested in the possible mechanisms that result in dynamically induced …

Generating and protecting high fidelity multi-particle entangled states with atom-photon interactions
… interactions to produce multi-particle quantum states of atoms. After reviewing the basic challenges associated with engineering atomphoton interactions and techniques for overcoming these, we first describe “counter-factual” carving, a new method that harnesses curious properties of …

Manipulation of photonic quantum states: From generation, engineering, and characterization to storage and retrieval
The quantum state is the building block of every technology based on quantum mechanics. Its manipulation is critical for real applications, and is thus an important area of investigation within various physical systems, even after decades of study. As one of the types of information carrier, the …
