Ion trap on borosilicate substrate with integrated femtosecond-laser-written waveguide
Jakob Wahl, Alexander Zesar, Philipp Hurdax +9
We present an ion-trap platform on borosilicate glass with an integrated femtosecond-laser-written waveguide for on-chip light delivery. The optical layer is physically separated f…
Demonstration of transport in an ion trap design for two-dimensional lattices
Michael Pfeifer, Marco Valentini, Matthias Dietl +7
Microfabricated ion trap chips are at the core of some of the most advanced quantum computers. How a large number of ions is arranged and controlled on an ion trap chip depends on…
Demonstration of two-dimensional connectivity for a scalable error-corrected ion-trap quantum processor architecture
Marco Valentini, Martin W. van Mourik, Friederike Butt +12
A major hurdle for building a large-scale quantum computer is increasing the number of qubits while maintaining connectivity between them. In trapped-ion devices, this connectivity…
Femtosecond laser written waveguides in sapphire for visible light delivery
Sarah Winkler, Joachim R. Krenn, Jakob Wahl +8
A promising solution for scalable integrated optics of trapped-ion quantum processors are curved waveguides guiding visible light within sapphire bulk material. To the best of our…
