Transition from Collective to Local Radial Motional Modes in a Tapered Paul Trap
Manika Bhardwaj, Moritz Göb, Bogomila S. Nikolova +3
With coupled detuned oscillators, either individual or collective oscillations are observable. The latter is used in quantum information processing in linear Paul traps. Here, we s…

Adiabatic Ramsey Interferometry for Measuring Weak Nonlinearities with Super-Heisenberg Precision
Venelin P. Pavlov, Bogomila S. Nikolova, Peter A. Ivanov
We propose an adiabatic Ramsey interferometry technique for detecting weak nonlinearities with trapped ions. The method relies on using the quantum Rabi model as a probe, which is…

Mechanical Squeezed Kerr Oscillator based on Tapered Ion Trap
Bogomila S. Nikolova, Motitz Göb, Kilian Singer +1
We propose the realization of a mechanically squeezed Kerr oscillator with a single ion in a tapered trap. We show that the motion coupling between the axial and radial modes cause…
