Non-linear cooling and control of a mechanical quantum harmonic oscillator
Matteo Simoni, Ivan Rojkov, Matteo Mazzanti +7
Non-linearities are a key feature allowing non-classical control of quantum harmonic oscillators. However, when non-linearities are strong, designing protocols for control is often…
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…
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…
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…
