The main aim of our current research activities is the development and construction of a Coplanar Waveguide-cavity Penning trap: a new planar Penning trap technology based upon Coplanar Waveguide (CPW) transmission-lines.
The CPW is a planar transmission line, consisting of a central conducting strip and two flanking ground-planes. Quasi-TEM microwaves can propagate along this transmission line, with frequencies 1 – 50 GHz. CPW cavities with very high quality factors Q = 105, or higher, can be fabricated with superconducting materials. Such cavities are able to store a single MW photon and are the basis of circuit-quantum electrodynamics (circuit-QED) experiments with superconducting artificial atoms.
Genesis of the CPW-cavity Penning trap
The novel Coplanar Waveguide cavity Penning trap results from the projection of the well-known cylindrical Penning trap onto the surface of a chip.
The CPW-cavity trap can be directly integrated within circuit-QED quantum networks, providing those with a very powerful experimental tool, namely a geonium atom.
