Deep-Learning-Designed AlGaAs Interface Linking Trapped Ions to Telecom Quantum Networks
I. P. De Simeone, G. Maltese, V. Cambier +5
The realization of a scalable quantum internet requires efficient light-matter interfaces that map stationary qubits onto photonic carriers for long-distance transmission. A centra…
Incoherent repumping scheme in the Sr five-level manifold
Valentin Martimort, Sacha Guesne, Derwell Drapier +6
Laser-cooled trapped ions are at the heart of modern quantum technologies and their cooling dynamics often deviate from the simplified two-level atom model. Doppler cooling of the…
TSV-integrated Surface Electrode Ion Trap for Scalable Quantum Information Processing
P. Zhao, J. -P. Likforman, H. Y. Li +6
In this study, we report the first Cu-filled through silicon via (TSV) integrated ion trap. TSVs are placed directly underneath electrodes as vertical interconnections between ion…
Functional surface ion traps on a 12-inch glass wafer for quantum applications
J Tao, J Likforman, P Zhao +6
We report large-scale fabrication of perfectly functional radio frequency (RF) surface ion traps on a 12-inch glass substrate with a standard CMOS-compatible backend process. Estab…
Absolute Single Ion Thermometry
Vincent Tugayé, Jean-Pierre Likforman, Samuel Guibal +1
We describe and experimentally implement a single-ion local thermometry technique with absolute sensitivity adaptable to all laser-cooled atomic ion species. The technique is based…
Precision measurement of the branching fractions of the 5p 2 P 1/2 state in 88 Sr + with a single ion in a micro fabricated surface trap
Jean-Pierre Likforman, Vincent Tugayé, Samuel Guibal +1
We measured the branching fractions for the decay of the 5p 2 P 1/2 state of 88 Sr + by applying a recently demonstrated photon-counting sequential method (M. Ramm et al., Phys. Re…
Isotope shifts of natural Sr+ measured by laser fluorescence in a sympathetically cooled Coulomb crystal
Brice Dubost, Romain Dubessy, Benjamin Szymanski +3
We measured by laser spectroscopy the isotope shifts between naturally-occurring even-isotopes of strontium ions for both the (violet) and the…
Large 2D Coulomb crystals in a radio frequency surface ion trap
B. Szymanski, R. Dubessy, B. Dubost +3
We designed and operated a surface ion trap, with an ion-substrate distance of 500\mum, realized with standard printed-circuit-board techniques. The trap has been loaded with up to…
Quantum correlations by four-wave mixing in an atomic vapor in a non-amplifying regime: a quantum beam splitter for photons
Quentin Glorieux, Luca Guidoni, Samuel Guibal +2
We study the generation of intensity quantum correlations using four-wave mixing in a rubidium vapor. The absence of cavity in these experiments allows to deal with several spatial…
Double-lambda microscopic model for entangled light generation by four-wave-mixing
Q. Glorieux, R. Dubessy, S. Guibal +4
Motivated by recent experiments, we study four-wave-mixing in an atomic double-Λ system driven by a far-detuned pump. Using the Heisenberg-Langevin formalism, and based on the micr…
Strong quantum correlations in four wave mixing in Rb vapor
Quentin Glorieux, Luca Guidoni, Samuel Guibal +2
We study quantum intensity correlations produced using four-wave mixing in a room-temperature rubidium vapor cell. An extensive study of the effect of the various parameters allows…
Photoionisation loading of large Sr+ ion clouds with ultrafast pulses
Sébastien Removille, Romain Dubessy, Quentin Glorieux +4
This paper reports on photoionisation loading based on ultrafast pulses of singly-ionised strontium ions in a linear Paul trap. We take advantage of an autoionising resonance of Sr…
