Phase gate and readout with an atom/molecule hybrid platform (2009)
Kuznetsova, Elena, Gacesa, Marko, Yelin, Susanne F., Côté, Robin
We suggest a combined atomic/molecular system for quantum computation, which takes advantage of highly developed techniques to control atoms and recent experimental progress in manipulation of...
Potential energy surface of the 2A' Li2+Li doublet ground state (2009)
Byrd, Jason N., Montgomery Jr., John A., Michels, H. Harvey, Côté, Robin
The lowest doublet electronic state for the lithium trimer (2A') is calculated for use in three-body scattering calculations using the valence electron FCI method with atomic cores represented using...
Kuznetsova, Elena, Yelin, Susanne F., Gacesa, Marko, Pellegrini, Philippe, Côté, Robin
We develop a complete theoretical description of photoassociative Stimulated Raman Adiabatic Passage (STIRAP) near a Feshbach resonance in a thermal atomic gas. We show that it is possible to use low...
Giant formation rates of ultracold molecules via Feshbach Optimized Photoassociation (2008)
Pellegrini, Philippe, Gacesa, Marko, Côté, Robin
Ultracold molecules offer a broad variety of applications, ranging from metrology to quantum computing. However, forming "real" ultracold molecules, {\it i.e.} in deeply bound levels, is a very...
Formation of deeply bound molecules via chainwise adiabatic passage (2008)
Kuznetsova, Elena, Pellegrini, Philippe, Côté, Robin, Lukin, M. D., Yelin, S. F.
We suggest and analyze a novel technique for efficient and robust creation of dense ultracold molecular ensembles in their ground rovibrational state. In our approach a molecule is brought to the...
Kuznetsova, Elena, Côté, Robin, Kirby, Kate, Yelin, Susanne
We analyse recently proposed physical implementations of a quantum computer based on polar molecules. A set of general requirements for a molecular system is presented, which would provide an optimal...
Feshbach resonances in ultracold ^{6,7}Li + ^{23}Na atomic mixtures (2007)
Gacesa, Marko, Pellegrini, Philippe, Côté, Robin
We report a theoretical study of Feshbach resonances in $^{6}$Li + $^{23}$Na and $^{7}$Li + $^{23}$Na mixtures at ultracold temperatures using new accurate interaction potentials in a full quantum...
Spectroscopic Temperature Determination of Degenerate Fermi Gases (2003)
We suggest a simple method for measuring the temperature of ultra-cold gases made of fermions. We show that by using a two-photon Raman probe, it is possible to obtain lineshapes which reveal...
Collisional properties of trapped cold chromium atoms (2003)
Pavlovic, Zoran, Roos, Björn O., Côté, Robin, Sadeghpour, H. R.
We report on calculations of the elastic cross section and thermalization rate for collision between two maximally spin-polarized chromium atoms in the cold and ultracold regimes, relevant to...
