Imaging the collective excitations of an ultracold gas using statistical correlations
Romain Dubessy, Camilla De Rossi, Thomas Badr +2
Advanced data analysis techniques have proved to be crucial for extracting information from noisy images. Here we show that principal component analysis can be successfully applied…
Robust preparation and manipulation of protected qubits using time--varying Hamiltonians
Thomas Coudreau, Benoit Doucot, Romain Dubessy +2
We show that it is possible to initialize and manipulate in a deterministic manner protected qubits using time varying Hamiltonians. Taking advantage of the symmetries of the syste…
Quantum Repeaters based on Single Trapped Ions
Nicolas Sangouard, Romain Dubessy, Christoph Simon
We analyze the performance of a quantum repeater protocol based on single trapped ions. At each node, single trapped ions embedded into high finesse cavities emit single photons wh…
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…
