Oberseminar Wissenschaftliches Rechnen (Dr. Sara Nicoletti)

Abstract:

Single atoms movable from one place to another would enable a flying quantum memory that
can be useful for dynamic quantum computing architectures. Optical tweezers are versatile tools
in modern science, being used to trap and guide small particles like atoms. Single particles
manipulated at a few micrometers distance by optical tweezers are well suited to control and
investigate their interaction nature among themselves and with others, even at the quantum level.
Due to these motifs, single atoms in optical tweezers represent an interesting tool as quantum
information carrier. We study an optimal control problem for the transport of atoms trapped in
optical tweezers in order to replicate experimental conditions where tweezers are Gaussian-shape
potential and each atom can be represented as a thermal state.
