One of the biggest roadblocks currently in the way of large scale quantum computation is the limited relaxation times of the current state of the art quantum computers. This limitation is due to the use of superconducting qubits, which...
Notes from Paul Dirac covering multiple subjects, such as rotations in real space, e-vectors, and theory used to break down the ket matrix for the normal state.
Notes from the lecture given in Edinburgh, Scotland by Paul A. M. Dirac concerning where quantum mechanics originated and how the idea of antimatter spread among physicists.
The Standard Model (SM) of particle physics offers the most complete quantum description of the known universe to date, however is unable to address some still unanswered questions. Supersymmetry (SUSY) is a theory which proposes partner...
Lecture given by Paul A. M. Dirac at the Lindau Nobel Laureate Conference concerning the basis of quantum mechanics and the recent problems quantum theory faced.
This dissertation is a theoretical and computational examination of structural, electronic and magnetic properties of complex transition metal oxide structures. Our work is motivated by experimental observations that transition metal...
Manual Nuclear Magnetic Resonance (NMR) spectral analysis of proteins is a time intensive effort with methods often specific to each analysis. The method described in this thesis automates the resonance assignment of protein side chains...
Letter sent from the Cambridge Mathematical Club announcing a club meeting on February 8, 1928, at which Dr. Dirac will read a paper on "The New Mechanics."
Proofs and theories relating to relativistic dynamics by P.A.M. Dirac, covering topics from single particle dynamics, free particles, and classical mechanics of particles.
In this work we study quantum non-relativistic three-body systems interacting via Coulomb potential. The solution in this undertaking utilizes and expansion of wave functions using products of Laguerre polynomial, followed by variational...
A quantum computer is a device that exploits the strange properties of quantum mechanics in order to perform computations that are not feasible on a classical computer. To implement a quantum computer, it will be necessary to maintain...
Notes on the principles of quantum mechanics. Chapter 1 covers the principles of superposition including waves and particles, the polarization of photons, and the compatibility of observations.
This dissertation explores the integration of quantum electrodynamics (QED) with electronic structure theory to accurately model and understand complex light-matter interactions within optical cavities. Clever designs of optical cavities...
Proofs from Paul Dirac covering symplectic space, transformations in symplectic space, bounded vectors and what they represent, and that there is a vector of infinite length for an unbounded matrix.
Notes on the lecture which Paul A. M. Dirac presented at the University of Cambridge. The lecture discusses the Bohr-Summerfeld theory, the Heisenberg principle, and Dirac's own equation.
Notes on quantum mechanics written by Paul A. M. Dirac. The preface includes a brief explanation on the need for the newer concept of quantum mechanics, the difficulties in this field of science, and discussion of Dirac's own theory....
Lecture given by Paul A. M. Dirac at two different conferences in Paris, France on December 16 and 23, 1930. Lecture introduces the new idea of quantum physics and explaining the major differences between that and the older, more ...
Letter sent from Haarlem by H.A. Lorentz to Dr. Dirac discussing his theory and inviting him to join the physics department at the university for a year.
Letter from Leipzig by P. Debye to Dr. Dirac regarding an upcoming discussion on quantum theory and chemistry and requesting Dr. Dirac give an address at the meeting.
Proofs by Paul Dirac for the combination of theories in order to relate them back to particles and how they behave in waves. Some theories and laws include: classical electron equation of motion in de Sitter space, Riess Theory, ...
The properties of quantum spins diluted in non-magnetic crystals make them a promising candidatefor a quantum memory given their long coherence and relaxation times and their limited Hilbert space span by the electron and nuclear states...
Essays, diagrams, and general notes from Paul Dirac on a number of topics including q-number variables, representation of electromagnetic fields as equations, dispersion theory, and the two fundamental spinors (according to Dirac).
Letter sent from Haarlem by H.A. Lorentz to Dr. Dirac inviting him to join the discussion on modern quantum dynamics at the Institut international du Physique-Solvay in the upcoming October.
Letter sent from Y. Breit to Dr. Dirac asking for his plans for the year and the possibility of working together. Breit also poses a few questions about Dr. Dirac's theories.
As the discovery of quantum mechanics signified a revolution in the world of physics more than one century ago, the notion of a quantum computer in 1981 marked the beginning of a drastic change of our understanding of information and...
Letter sent from Leipzig by Werner Heisenberg to Dr. Dirac discussing the possibility of working together in Chicago in the fall as well as their recent work and theories.
