Global Variational Quantum Circuits for Arbitrary Symmetric State Preparation
Liam J. Bond, Matthew J. Davis, JiÅà MináŠ+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…
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…
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…
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…
