Progress towards dipole-phonon quantum logic with trapped ions

POSTER

Abstract

Molecular ions are proposed to be promising candidates for high precision measurements of fundamental constants, cold chemistry dynamics control, and quantum information processing. Particularly with regards to quantum computer engineering, the rich internal structures and long range dipole-dipole interactions between molecular ions offer a means of potentially overcoming some of the current problems of atomic ion platforms. \footnote{E. Hudson and W. Campbell, 10.1103/PhysRevA.98.040302.}\footnote{ W. Campbell and E. Hudson, arXiv:1909.02668.}. Here, we report our progress towards dipole-phonon interaction with molecular and atomic ions. A Calcium ion is cooled near its motional ground state and is used to excite a dipole transition of a co-trapped molecular ion by delicately controlling the phonons. Progress towards dipole-phonon logic gate is also presented.
