Quantum disentanglement eraser: A cavity QED implementation
(American Physical Society, 2004-07-29)A possible experimental scheme of the Garisto-Hardy disentanglement eraser based on a cavity QED system is presented. This scheme can be used for a delayed choice quantum eraser. It also allows us to acquire single-qubit ... -
Quantum dots for Photovoltaic Applications
(2017-11)During the past century, impacts of climate change on both natural and human systems have been observed worldwide. Numerous scientific investigations suggest a strong correlation between the global warming and greenhouse ... -
Quantum Effects in Nodal-line Semimetals
(2020)Topological materials such as Dirac and Weyl semimetals have relativistic quasiparticles at a discrete number of points in the Brillouin zone. Those materials are semimetalas in the bulk but host metallic surface states ... -
Quantum Hall ferromagnetism in indium antimonide quantum wells.
(2005)Antimony-based III-V semiconductors are getting increasing attention for device applications and fundamental research thanks to advances made in their growth and understanding of their properties. InSb with its extremely ... -
Quantum imaging and sensing with entangled photons
(2008-07)This dissertation contains new theoretical work on how to utilize the entangled photons produced in a parametric down conversion to improve resolution and sensitivity in quantum interferometry, magnetometry and lithography. ... -
Quantum imaging with incoherent photons
(American Physical Society, 2007-09-28)We propose a technique to obtain subwavelength resolution in quantum imaging with potentially 100% contrast using incoherent light. Our method requires neither path-entangled number states nor multiphoton absorption. The ... -
Quantum interference and decoherence effects in novel systems
(2009-12)In this thesis we studied quantum interference and decoherence effects in systems like atoms, ions, quantum dots and photonic waveguides. These systems are presently widely studied in different areas of quantum optics and ... -
Quantum interferences in cooperative Dicke emission from spatial variation of the laser phase
(American Physical Society, 2008-10-06)We report generation of a new quantum interference effect in spontaneous emission from a resonantly driven system of two identical two-level atoms due to the spatial variation of the laser phase at the positions of the ... -
Quantum logic gates using Stark-shifted Raman transitions in a cavity
(American Physical Society, 2004-06-04)We present a scheme to realize the basic two-qubit logic gates such as quantum phase gate and controlled-NOT gate using a detuned optical cavity interacting with a three-level Raman system. We discuss the role of Stark ... -

Quantum model of human subjectivity for moral psychology: Using Q methodology to define the features of judgments in Hilbert space
(2018-05)A major issue in the field of moral psychology is identifying aspects of human morality that can be measured. Kantor's (1959) formulation of a psychological event provides a unique option for the field. A psychological ... -
QUANTUM MONTE CARLO STUDY OF BOSONIC LATTICE SYSTEMS IN THE PRESENCE OF DISORDER
(2018-08-30)Disorder is ubiquitous in condensed matter systems, but a thorough understanding of these systems is hindered by poor control over the nature of disorder and competing interactions. Ultracold gases trapped in optical ... -
Quantum optical spring
(American Physical Society, 2008-07-22)We study the dynamics of the quantum optical spring, i.e., a spring whose spring constant undergoes discrete jumps depending on the quantum state of another system. We show the existence of revivals and fractional revivals ... -
Quantum Plasmonic Sensing Using Squeezed Light
(2021-08-05)Quantum sensing is an emerging field of quantum optics that seeks to take advantage of quantum correlations available in quantum states of light to enable sensitivities beyond the fundamental classical limits. The sensitivity ... -
Quantum random walk of the field in an externally driven cavity
(American Physical Society, 2005-09-16)Using a resonant interaction between atoms and the field in a high-quality cavity, we show how to realize quantum random walks as proposed by Aharonov et al. [Phys. Rev. A 48, 1687 (1993)]. The atoms are driven strongly ... -

QUANTUM SECURE COMMUNICATION USING POLARIZATION HOPPING MULTI-STAGE PROTOCOLS
(2016)This dissertation presents a study of the security and performance of a quantum communication system using multi-stage multi-photon tolerant protocols. Multi-stage protocols are a generalization of the three-stage protocol ...
