The use of trapped atomic ions in the field of quantum information processing is briefly
reviewed. We summarize the basic mechanisms required for logic gates and the use of the …

We demonstrate trapping of electrons in a millimeter-sized quadrupole Paul trap driven at
1.6 GHz in a room-temperature ultrahigh vacuum setup. Cold electrons are introduced into …

Electrons and ions trapped with electromagnetic fields have long served as important high-
precision metrological instruments, and more recently have also been proposed as a …

We investigate the feasibility of using electrons in a linear Paul trap as qubits in a future
quantum computer. We discuss the necessary experimental steps to realize such a device …

Trapped charged particles have been at the forefront of quantum information processing
(QIP) for a few decades now, with deterministic two-qubit logic gates reaching record …

The manipulation of individual charged particles has been deeply explored in physics's
theoretical and experimental domains during the past decades. It is the pillar of several …

A one-electron qubit would offer a new option for quantum information science, including the
possibility of extremely long coherence times. One-quantum cyclotron transitions and spin …

We demonstrate the transverse confinement and guiding of a low energy electron beam of
several electron volts in a miniaturized linear quadrupole guide. The guiding potential is …

Ion-ion coupling over long distances represents a highly useful resource for quantum
technologies, for example, to sympathetically cool or interconnect qubits in ion-based …

We describe a versatile planar Penning trap structure, which allows one to dynamically
modify the trapping configuration almost arbitrarily. The trap consists of 37 hexagonal …
