    • The quadratic Zeeman effect in hydrogen 

      Richter, Burton, 1931- (Massachusetts Institute of Technology, 1952)
    • Quality of care and drug surveillance : a data-driven perspective 

      Czerwinski, David (David E.) (Massachusetts Institute of Technology, 2008)
      In this thesis, we describe the use of medical insurance claims data in three important areas of medicine. First, we develop expert- trained statistical models of quality of care based on variables derived from insurance ...
    • Quantification of microRNA regulation and its consequences at the single cell level 

      Zheng, Yannan Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2015)
      MicroRNAs (miRNAs) are a class of small non-coding RNAs which play important roles in post transcriptional gene regulation. miRNAs regulate more than half of mammalian protein-coding genes. They have been found to participate ...
    • Quantifying galactic propagation uncertainty in WIMP dark matter search with AMS01 Z=-1 spectrum 

      Xiao, Sa, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
      A search for a WIMP dark matter annihilation signal is carried out in the AMS01 negatively charged (Z=-I) particle spectrum, following a set of supersymmetric benchmark scenarios in the mSUGRA framework. The result is ...
    • Quantitative phase microscopy for the study of electromotility in living cells 

      Oh, Seung-eun (Massachusetts Institute of Technology, 2010)
      The electric activity of living cells is accompanied with changes in their optical and mechanical properties, which arise from the intrinsic biophysics of the cell membrane. These intrinsic changes can be used as an indicator ...
    • Quantum algorithms 

      Abrams, Daniel S. (Daniel Stephen), 1972- (Massachusetts Institute of Technology, 1999)
    • Quantum beat spectroscopy of acetylene 

      Shah, Nisha N (Massachusetts Institute of Technology, 1986)
    • Quantum blackjack : quantum strategies and advantages in games with limited classical communication 

      Lin, Joseph Xiao (Massachusetts Institute of Technology, 2018)
      In this thesis, we examine the advantages that quantum strategies afford in communication-limited games. Inspired by the card game blackjack, we particularly focus on cooperative, two-party sequential games in which a ...
    • Quantum capacitance measurements of single-layer molybdenum disulfide 

      Kononov, Alina (Massachusetts Institute of Technology, 2014)
      Through this thesis, heterostructures composed of a thin layer of hexagonal boron nitride atop a monolayer of molybdenum disulfide were fabricated with the goal of measuring quantum capacitance and probing the transition ...
    • Quantum codes on Hurwitz surfaces 

      Kim, Isaac H. (Isaac Hyun) (Massachusetts Institute of Technology, 2007)
      Ever since the birth of the first quantum error correcting code, many error correcting techniques and formalism has been constructed so far. Among those, generating a quantum code on a locally planar geometry have lead to ...
    • Quantum coherence and magnetism in bosonic and fermionic gases of ultracold atoms 

      Jo, Gyu-Boong (Massachusetts Institute of Technology, 2010)
      In this thesis, two sets of experimental studies in bosonic and fermionic gases are described. In the first part of the thesis, itinerant ferromagnetism was studied in a strongly interacting Fermi gas of ultracold atoms. ...
    • Quantum computation beyond the circuit model 

      Jordan, Stephen Paul (Massachusetts Institute of Technology, 2008)
      The quantum circuit model is the most widely used model of quantum computation. It provides both a framework for formulating quantum algorithms and an architecture for the physical construction of quantum computers. However, ...

    • Quantum electronic transport in atomically layered topological insulators 

      Fatemi, Valla (Massachusetts Institute of Technology, 2018)
      The merger of topology and symmetry established a new foundation for understanding the physics of condensed matter, beginning with the notion of topological insulators (TIs) for electronic systems. For the time-reversal ...
    • Quantum enhanced sensing and communication 

      Zhuang, Quntao (Massachusetts Institute of Technology, 2018)
      Quantum phenomena such as entanglement and superposition enable performance beyond what classical physics can provide in tasks of computing, communication and sensing. Quantum sensing aims to enhance the measurement precision ...
    • Quantum field theory of scalar cosmological perturbations 

      Tassev, Svetlin Valentinov (Massachusetts Institute of Technology, 2005)
      Using canonical quantization we show that the spectrum of the scalar cosmological fluctuations as calculated until now is not correct. We derive the correct expression for the spectrum, and show that our correct treatment ...
    • Quantum gas microscopy of strongly correlated fermions 

      Cheuk, Lawrence W (Massachusetts Institute of Technology, 2017)
      This thesis describes experiments on ultracold fermionic atoms, and can be divided into two areas. The first concerns spin-orbit coupling; the second concerns quantum gas microscopy. With the use of Raman transitions, ID ...
