Experimental realization of nonunitary multi-qubit operations
Martin W. van Mourik, Elias Zapusek, Pavel Hrmo +5
We demonstrate a novel experimental toolset that enables irreversible multi-qubit operations on a quantum platform. To exemplify our approach, we realize two elementary nonunitary…
Native qudit entanglement in a trapped ion quantum processor
Pavel Hrmo, Benjamin Wilhelm, Lukas Gerster +6
Quantum information carriers, just like most physical systems, naturally occupy high-dimensional Hilbert spaces. Instead of restricting them to a two-level subspace, these high-dim…
RF-induced heating dynamics of non-crystallized trapped ions
Martin W. van Mourik, Pavel Hrmo, Lukas Gerster +4
We investigate the energy dynamics of non-crystallized (melted) ions, confined in a Paul trap. The non-periodic Coulomb interaction experienced by melted ions forms a medium for no…
Cryogenic setup for trapped ion quantum computing
M. F. Brandl, M. W. van Mourik, L. Postler +15
We report on the design of a cryogenic setup for trapped ion quantum computing containing a segmented surface electrode trap. The heat shield of our cryostat is designed to attenua…
Ultrafast electron diffraction using an ultracold source
M. W. van Mourik, W. J. Engelen, E. J. D. Vredenbregt +1
We present diffraction patterns from micron-sized areas of mono-crystalline graphite obtained with an ultracold and ultrafast electron source. We show that high spatial coherence i…
