Fast and robust quantum computation with ionic Wigner crystals
J. D. Baltrusch, A. Negretti, J. M. Taylor +1
We present a detailed analysis of the modulated-carrier quantum phase gate implemented with Wigner crystals of ions confined in Penning traps. We elaborate on a recent scheme, prop…
Quantum-noise quenching in atomic tweezers
Stefano Zippilli, Bernd Mohring, Eric Lutz +2
The efficiency of extracting single atoms or molecules from an ultracold bosonic reservoir is theoretically investigated for a protocol based on lasers, coupling the hyperfine stat…
Quantum jumps induced by the center-of-mass motion of a trapped atom
J. M. Torres, M. Bienert, S. Zippilli +1
We theoretically study the occurrence of quantum jumps in the resonance fluorescence of a trapped atom. Here, the atom is laser cooled in a configuration of level such that the occ…
Single-photon emission from Ni-related color centers in CVD diamond
David Steinmetz, Elke Neu, Christian Hepp +5
Color centers in diamond are very promising candidates among the possible realizations for practical single-photon sources because of their long-time stable emission at room temper…
Quantum Classical Correspondence for a non-Hermitian Bose-Hubbard Dimer
Eva-Maria Graefe, Hans Jürgen Korsch, Astrid Elisa Niederle
We investigate the many-particle and mean-field correspondence for a non-Hermitian N-particle Bose-Hubbard dimer where a complex onsite energy describes an effective decay from one…
Progress toward scalable tomography of quantum maps using twirling-based methods and information hierarchies
Cecilia C. López, Ariel Bendersky, Juan Pablo Paz +1
We present in a unified manner the existing methods for scalable partial quantum process tomography. We focus on two main approaches: the one presented in Bendersky et al. [Phys. R…
