Micromotion minimization using Ramsey interferometry
Gerard Higgins, Shalina Salim, Chi Zhang +3
We minimize the stray electric field in a linear Paul trap quickly and accurately, by applying interferometry pulse sequences to a trapped ion optical qubit. The interferometry seq…
Magic trapping of a Rydberg ion with a diminished static polarizability
Fabian Pokorny, Chi Zhang, Gerard Higgins +1
Highly excited Rydberg states are usually extremely polarizable and exceedingly sensitive to electric fields. Because of this Rydberg ions confined in electric fields have state-de…
Observation of effects due to an atom's electric quadrupole polarizability
Gerard Higgins, Chi Zhang, Fabian Pokorny +4
The response of matter to fields underlies the physical sciences, from particle physics to astrophysics, and from chemistry to biophysics. We observe an atom's response to an elect…
Sub-microsecond entangling gate between trapped ions via Rydberg interaction
Chi Zhang, Fabian Pokorny, Weibin Li +4
Generating quantum entanglement in large systems on time scales much shorter than the coherence time is key to powerful quantum simulation and computation. Trapped ions are among t…
Highly-polarizable ion in a Paul trap
Gerard Higgins, Fabian Pokorny, Chi Zhang +1
Usually the influence of the quadratic Stark effect on an ion's trapping potential is minuscule and only needs to be considered in atomic clock experiments. In this work we excite…
Tracking the dynamics of an ideal quantum measurement
Fabian Pokorny, Chi Zhang, Gerard Higgins +3
The existence of ideal quantum measurements is one of the fundamental predictions of quantum mechanics. In theory the measurement projects onto the eigenbasis of the measurement ob…
Coherent control of a single trapped Rydberg ion
Gerard Higgins, Fabian Pokorny, Chi Zhang +2
Trapped Rydberg ions are a promising novel approach to quantum computing and simulations. They are envisaged to combine the exquisite control of trapped ion qubits with the fast tw…
A single strontium Rydberg ion confined in a Paul trap
Gerard Higgins, Weibin Li, Fabian Pokorny +7
Trapped Rydberg ions are a promising new system for quantum information processing. They have the potential to join the precise quantum operations of trapped ions and the strong, l…
