Predicting electric-field noise in ion traps using fluctuation electrodynamics
Markus Teller, Da An, Alberto M. Alonso +4
Electric-field noise in microfabricated surface ion traps contributes to gate errors in trapped-ion quantum computers, but this noise has been challenging to predict. Here, we pres…
Hybrid Paul-optical trap with large optical access for levitated optomechanics
Eric Bonvin, Louisiane Devaud, Massimiliano Rossi +7
We present a hybrid trapping platform that allows us to levitate a charged nanoparticle in high vacuum using either optical fields, radio-frequency fields, or a combination thereof…
Ultra-high quality factor of a levitated nanomechanical oscillator
Lorenzo Dania, Dmitry S. Bykov, Florian Goschin +3
A levitated nanomechanical oscillator under ultra-high vacuum (UHV) is highly isolated from its environment. It has been predicted that this isolation leads to very low mechanical…
Entanglement of trapped-ion qubits separated by 230 meters
V. Krutyanskiy, M. Galli, V. Krcmarsky +13
We report on an elementary quantum network of two atomic ions separated by 230 m. The ions are trapped in different buildings and connected with 520(2) m of optical fiber. At each…
Integrating a fiber cavity into a wheel trap for strong ion-cavity coupling
Markus Teller, Viktor Messerer, Klemens Schüppert +6
We present an ion trap with an integrated fiber cavity, designed for strong coupling at the level of single ions and photons. The cavity is aligned to the axis of a miniature linea…
Heating of a trapped ion induced by dielectric materials
Markus Teller, Dario A. Fioretto, Philip C. Holz +8
Electric-field noise due to surfaces disturbs the motion of nearby trapped ions, compromising the fidelity of gate operations that are the basis for quantum computing algorithms. W…
Probing surface charge densities on optical fibers with a trapped ion
Florian R. Ong, Klemens Schüppert, Pierre Jobez +8
We describe a novel method to measure the surface charge densities on optical fibers placed in the vicinity of a trapped ion, where the ion itself acts as the probe. Surface charge…
