Average-Reward Policy Identification from a Single Continuing Trajectory
Tongxi Wang
In reinforcement learning, an agent must explore an unknown environment to learn how to make good decisions. Unlike methods that can freely sample any state--action pair, an agent…
Entangling ions with engineered light gradients
Tommaso Faorlin, Lorenz Panzl, Phoebe Grosser +12
Spectral crowding of collective motional modes limits the fidelity of entangling interactions in trapped-ion quantum processors by inducing off-resonant coupling to spectator modes…
Towards metrology with highly charged isomeric ions from antiproton annihilation
Sara Alfaro, Lorenz Panzl, Jakub Zieliński +10
We describe how the annihilation of antiprotons can be utilized to generate highly charged isomeric ions in an ion-trap setup. We identify optical transitions in the hyperfine spli…
Controlling the spontaneous emission of trapped ions
Tommaso Faorlin, Benjamin Yadin, Yannick Weiser +7
We propose an experimental setup for manipulating the spontaneous emission of trapped ions, based on a spatial light modulator. Anticipated novelties include the potential to entan…
TALOS (Total Automation of LabVIEW Operations for Science): A framework for autonomous control systems for complex experiments
M. Volponi, J. Zieliński, T. Rauschendorfer +52
Modern physics experiments are frequently very complex, relying on multiple simultaneous events to happen in order to obtain the desired result. The experiment control system plays…
Back action suppression for levitated dipolar scatterers
Yannick Weiser, Tommaso Faorlin, Lorenz Panzl +6
Levitated dipolar scatterers exhibit exceptional performance as optomechanical systems for observing quantum mechanics at the mesoscopic scale. However, their tendency to scatter l…
Position measurement of a levitated nanoparticle via interference with its mirror image
Lorenzo Dania, Katharina Heidegger, Dmitry S. Bykov +3
Interferometric methods for detecting the motion of a levitated nanoparticle provide a route to the quantum ground state, but such methods are currently limited by mode mismatch be…
Motion analysis of a trapped ion chain by single photon self-interference
G. Cerchiari, G. Araneda, L. Podhora +3
We present an optical scheme to detect the oscillations of a two-ion string confined in a linear Paul trap. The motion is detected by analyzing the intensity correlations in the fl…
Position measurement of a dipolar scatterer via self-homodyne detection
G. Cerchiari, L. Dania, D. S. Bykov +2
We describe a technique to measure the position of a dipolar scatterer based on self-homodyne detection of the scattered light. The method can theoretically reach the Heisenberg li…
Measuring ion oscillations at the quantum level with fluorescence light
G. Cerchiari, G. Araneda, L. Podhora +3
We demonstrate an optical method for detecting the mechanical oscillations of an atom with single-phonon sensitivity. The measurement signal results from the interference between t…
The Panopticon device: an integrated Paul-trap-hemispherical mirror system for quantum optics
Gabriel Araneda, Giovanni Cerchiari, Daniel B. Higginbottom +5
We present the design and construction of a new experimental apparatus for the trapping of single Ba ions in the center of curvature of an optical-quality hemispherical mirror.…
