Doctoral dissertation, Harvard University, Graduate School of Arts & Sciences.http://nrs.harvard.edu/urn-3:HUL.InstRepos:42013148This thesis summarizes two ongoing experiments. The primary focus is on progress towards realizing a single-electron qubit in a scalable, planar Penning trap geometry. Two simultaneously trapped electrons were observed, significant progress over previous attempts by others. The second topic is a review of work leading up to and following our laboratory's first production of cold antihydrogen atoms in 2002.application/pdfenPenning trap, antihydrogen, qubitThesis or Dissertation2019-12-11
