Universal, high-fidelity quantum gates based on superadiabatic, geometric phases on a solid-state spin-qubit at room temperature
Felix Kleißler, Andrii Lazariev, Silvia Arroyo-Camejo
Geometric phases and holonomies (their non-commuting generalizations) are a promising resource for the realization of high-fidelity quantum operations in noisy devices, due to thei…

A high numerical aperture (NA = 0.92) objective lens for imaging and addressing of cold atoms
Carsten Robens, Stefan Brakhane, Wolfgang Alt +5
We have designed, built, and characterized a high-resolution objective lens that is compatible with an ultra-high vacuum environment. The lens system exploits the principle of the…
