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…
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…
Reduction of heating rate in a microfabricated ion trap by pulsed-laser cleaning
D T C Allcock, L Guidoni, T P Harty +4
Laser-cleaning of the electrodes in a planar micro-fabricated ion trap has been attempted using ns pulses from a tripled Nd:YAG laser at 355nm. The effect of the laser pulses at se…
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…
Electric field noise above surfaces: a model for heating rate scaling law in ion traps
Romain Dubessy, Thomas Coudreau, Luca Guidoni
We present a model for the scaling laws of the electric field noise spectral density as a function of the distance, , above a conducting surface. Our analytical approach models…
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…
Feasibility of a quantum memory for continuous variables based on trapped ions
Thomas Coudreau, Frédéric Grosshans, Samuel Guibal +1
We propose to use a large cloud of cold trapped ions as a medium for quantum optics and quantum information experiments. Contrary to most recent realizations of qubit manipulation…
