Realisation of homogeneous ion chain using surface traps
J. Pedregosa-Gutierrez, M. Mukherjee
In a Radio-Frequency linear ion trap, 1D ion chains are routinely generated in laboratories around the world. They present a non-homogenous ion density along the chain. The possibi…
An analytical approach to symmetry breaking in multipole RF-traps
Marylise Marchenay, Jofre Pedregosa-Gutierrez, Martina Knoop +2
Radio-frequency linear multipole traps have been shown to be very sensitive to mis-positioning of their electrodes, which results in a symmetry breaking and leads to extra local mi…
Experimental Demonstration of a Terahertz Frequency Reference based on Coherent Population Trapping
Mathieu Collombon, Cyril Chatou, Gaétan Hagel +4
A novel protocol of interrogation based on coherent population trapping in an N-level scheme atomic system leads to dark resonances involving three different photons. An ensemble o…
Experimental demonstration of an efficient number diagnostic for long 1D ion chains
Marius Romuald Kamsap, Caroline Champenois, J. Pedregosa-Gutierrez +2
Very long, one-dimensional (1D) ion chains are the basis for many applications, in particular in quantum information processing and reliable diagnostics are needed to quantify them…
Coherent internal state transfer by three-photon STIRAP-like scheme for many-atom samples
Marius Romuald Kamsap, Thierry Blanchard Ekogo, Jofre Pedregosa-Gutierrez +5
A STIRAP-like scheme is proposed to exploit a three-photon resonance taking place in alkaline-earth-metal ions. This scheme is designed for state transfer between the two fine stru…
