Sub-Doppler cooling of trapped ions using optical tweezers
Bas Gerritsen, Liam J. Bond, Jiri Minář +3
We propose a sub-Doppler cooling scheme for trapped-ion crystals in Paul traps. The combination of a hollow tweezer and microwave drive creates an effective two-level system which…
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…
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…
Vibrationally coupled Rydberg atom-ion molecules
Ilango Maran, Liam J. Bond, Jeremy T. Young +2
We study the occurrence of Rydberg atom-ion molecules (RAIMs) in a hybrid atom-ion system with an ion crystal trapped in a Paul trap coupled to Rydberg atoms on its either ends. To…
Phonon-mediated quantum gates in trapped ions coupled to an ultracold atomic gas
Lorenzo Oghittu, Arghavan Safavi-Naini, Antonio Negretti +1
We study the dynamics of phonon-mediated qubit-qubit interactions between trapped ions in the presence of an ultracold atomic gas. By deriving and solving a master equation to desc…
Global Variational Quantum Circuits for Arbitrary Symmetric State Preparation
Liam J. Bond, Matthew J. Davis, Jiří Minář +3
Quantum states that are symmetric under particle exchange play a crucial role in fields such as quantum metrology and quantum error correction. We use a variational circuit compose…
Engineering spin-spin interactions with optical tweezers in trapped ions
Juan Diego Arias Espinoza, Matteo Mazzanti, Katya Fouka +5
We propose a new method for generating programmable interactions in one- and two-dimensional trapped-ion quantum simulators. Here we consider the use of optical tweezers to enginee…
Phonon-mediated spin-spin interactions between trapped Rydberg atoms
Rasmus Vestergaard Skannrup, R. Gerritsma, S. J. J. M. F. Kokkelmans
We theoretically investigate the possibility of creating phonon-mediated spin-spin interactions between neutral atoms trapped in optical tweezers. By laser coupling the atoms to Ry…
