Ultracold collisions of a neutral atom with a trapped ion in 1D
Seth T. Rittenhouse, Lorenzo Oghittu, Arghavan Safavi-Naini +2
We present a fully quantum mechanical description of a free Li atom scattering from a trapped Yb ion in one dimension. By reformulating the system in polar coordina…
Confinement-induced resonances for the creation of quasi-one-dimensional ultra cold gases of alkali--alkaline-earth dimers
Lorenzo Oghittu, Premjith Thekkeppatt, Nirav P. Mehta +4
We theoretically investigate the role of confinement-induced resonances (CIRs) in low-dimensional ultracold atomic mixtures for the formation of weakly bound dimers. To this end, w…
Quadratic spin-phonon coupling and bipolarons in trapped ions
L. P. H. Gallagher, M. Mazzanti, Z. E. D. Ackerman +3
We consider the quantum simulation of quadratic spin-phonon coupling in a crystal of trapped ions. The coupling is implemented using tightly focused optical tweezers on each ion th…
Non-paraxial effects on laser-qubit operations
L. P. H. Gallagher, M. Mazzanti, Z. E. D. Ackerman +3
Tightly-focused laser beams, or optical tweezers, are essential for analogue and digital quantum simulation with neutral atoms and trapped ions. Despite this, most of the current i…
Alignment and Optimisation of Optical Tweezers on Trapped Ions
M. Mazzanti, C. Robalo Pereira, N. A. Diepeveen +7
This paper presents a routine to align an optical tweezer on a single trapped ion and use the ion as a probe to characterize the tweezer. We find a smallest tweezer waist of $2.3(2…
Fast quantum state preparation and bath dynamics using non-Gaussian variational ansatz and quantum optimal control
Liam J. Bond, Arghavan Safavi-Naini, Jiří Minář
We combine quantum optimal control with a variational ansatz based on non-Gaussian states for fast, non-adiabatic preparation of quantum many-body states. We demonstrate this on th…
