Hybrid Microwave Radiation Patterns for High-Fidelity Quantum Gates with Trapped Ions
I. Arrazola, M. B. Plenio, E. Solano +1
We present a method that combines continuous and pulsed microwave radiation patterns to achieve robust interactions among hyperfine trapped ions placed in a magnetic field gradient…
A high-gain Quantum free-electron laser: emergence & exponential gain
Peter Kling, Enno Giese, C. Moritz Carmesin +2
We derive an effective Dicke model in momentum space to describe collective effects in the quantum regime of a free-electron laser (FEL). The resulting exponential gain from a sing…
Randomisation of Pulse Phases for Unambiguous and Robust Quantum Sensing
Zhen-Yu Wang, Jacob E. Lang, Simon Schmitt +6
We develop theoretically and demonstrate experimentally a universal dynamical decoupling method for robust quantum sensing with unambiguous signal identification. Our method uses r…
Initialization and Readout of Nuclear Spins via negatively charged Silicon-Vacancy Center in Diamond
Mathias H. Metsch, Katharina Senkalla, Benedikt Tratzmiller +7
In this work, we demonstrate initialization and readout of nuclear spins via a negatively charged silicon-vacancy (SiV) electron spin qubit. Under Hartmann-Hahn conditions the elec…
Proper time in atom interferometers: Diffractive versus specular mirrors
Enno Giese, Alexander Friedrich, Fabio Di Pumpo +4
We compare a conventional Mach-Zehnder light-pulse atom interferometer based on diffractive mirrors with one that uses specular reflection. In contrast to diffractive mirrors that…
Precursors of non-Markovianity
Steve Campbell, Maria Popovic, Dario Tamascelli +1
Using the paradigm of information backflow to characterize a non-Markovian evolution, we introduce so-called precursors of non-Markovianity, i.e. necessary properties that the syst…
