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…
Trapped Ion Quantum Computing using Optical Tweezers and the Magnus Effect
M. Mazzanti, R. Gerritsma, R. J. C. Spreeuw +1
We consider the implementation of quantum logic gates in trapped ions using tightly focused optical tweezers. Strong polarization gradients near the tweezer focus lead to qubit-sta…
Trapped Ion Quantum Computing using Optical Tweezers and Electric Fields
M. Mazzanti, R. X. Schüssler, J. D. Arias Espinoza +3
We propose a new scalable architecture for trapped ion quantum computing that combines optical tweezers delivering qubit state-dependent local potentials with oscillating electric…
