Our group has recently realized an entangling quantum logic gate in a surface-electrode ion trap using microwave fields that are produced by a custom microwave "antenna" embedded into the chip surface. In the "standard" ion trap quantum logic approach, such gates are realized using tightly focused...

The Trapped Ion Quantum Engineering group is part of the "MicroQC" consortium (U Sofia, U Siegen, U Sussex, HU Jerusalem, LUH and PTB) which aims to develop methods for scalable quantum computing with trapped ions based on microwave technology. Within the quantum technologies flagship, the EU will...

We have loaded our first 9Be+ ions into a cryogenic Penning trap on Friday October 26th! Ions were loaded using laser ablation from a solid Beryllium target, combined with two-photon ionization. The picture shows a cloud of 9Be+ ions, imaged by shining a laser beam resonant with the S_1/2 m_J=1/2 ->...

We have demonstrated ground state cooling of 9Be+ ions using microwave fields produced by a custom microwave "antenna" embedded into a surface-electrode ion trap. The viewgraph shows the suppression of the red (cooling) sideband which occurs close to the motional ground state, while the blue...
