All-Optical Universal Control of Hyperfine Qudits in Trapped Neutral Atoms
Johannes K. Krondorfer, Matthias Diez, Andreas Kruckenhauser +1
Quantum systems with more than two levels so-called qudits offer increased computational density and reduced circuit complexity compared to qubit-based architectures, but a…
Kapitza's Pendulum as a Classical Prelude to Floquet-Magnus Theory
Johannes K. Krondorfer, Maria Kainz, Matthias Diez +1
We present a pedagogical introduction to Floquet-Magnus theory through the classical example of Kapitza's pendulum - a simple system exhibiting nontrivial dynamical stabilization u…
Magnetic coupling between nuclear motion and nuclear spins in molecules
Matthias Diez, Johannes K. Krondorfer, Albert Hirtenfelder +1
Among the possible types of magnetic dipole interactions in molecular systems, couplings between nuclear motion and the nuclear spin have probably received the least attention in m…
Single Qudit Control in Sr via Optical Nuclear Electric Resonance
Johannes K. Krondorfer, Matthias Diez, Andreas W. Hauser
Optical nuclear electric resonance (ONER) was recently proposed as a fast and robust single-qubit gate mechanism in Sr. Here, we demonstrate through numerical simulations th…
Optical nuclear electric resonance as single qubit gate for trapped neutral atoms
Johannes K. Krondorfer, Sebastian Pucher, Matthias Diez +2
The precise control of nuclear spin states is crucial for a wide range of quantum technology applications. Here, we propose a fast and robust single-qubit gate in Sr, utiliz…
Molecular Pseudorotation in Phthalocyanines as a Tool for Magnetic Field Control at the Nanoscale
Raphael Wilhelmer, Matthias Diez, Johannes K. Krondorfer +1
Metal phthalocyanines, a highly versatile class of aromatic, planar, macrocyclic molecules with a chelated central metal ion, are topical objects of ongoing research and particular…
