High-fidelity quantum control via Autler-Townes splitting
Michele Delvecchio, Teodora Kirova, Ennio Arimondo +2
We propose quantum control protocols for the high-fidelity preparation of target states in systems with Autler-Townes splitting. We investigate an approximated three-level system o…
Parrondo's paradox for discrete-time quantum walks in momentum space
Georg Trautmann, Caspar Groiseau, Sandro Wimberger
We investigate the possibility of implementing a sequence of quantum walks whose probability distributions give an overall positive winning probability, while it is negative for th…
Classical model for survival resonances close to Talbot time
Mikkel F. Andersen, Sandro Wimberger
We present a classical approximation for the peaks of survival resonances occurring when diffracting matter waves from absorption potentials. Generally our simplified model describ…
Quantum to Classical Walk Transitions Tuned by Spontaneous Emissions
J. H. Clark, C. Groiseau, Z. N. Shaw +5
We have realized a quantum walk in momentum space with a rubidium spinor Bose-Einstein condensate by applying a periodic kicking potential as a walk operator and a resonant microwa…
Counteracting dephasing in Molecular Nanomagnets by optimized qudit encodings
Francesco Petiziol, Alessandro Chiesa, Sandro Wimberger +2
Molecular Nanomagnets may enable the implementation of qudit-based quantum error-correction codes which exploit the many spin levels naturally embedded in a single molecule, a prom…
Quantum simulation of three-body interactions in weakly driven quantum systems
Francesco Petiziol, Mahdi Sameti, Stefano Carretta +2
The realization of effective Hamiltonians featuring many-body interactions beyond pairwise coupling would enable the quantum simulation of central models underpinning topological p…
