Enhanced Parameter Estimation with Periodically Driven Quantum Probe
Entropy, 2021 I propose a quantum metrology protocol for measuring frequencies and weak forces based on a periodic modulating quantum Jahn–Teller system composed of a single spin and two bosonic modes.

Robust polarization gradient cooling of trapped ions
New Journal of Physics, 2022 We implement three-dimensional polarization gradient cooling (PGC) of trapped ions. Counter-propagating laser beams near 393 nm impinge in lin ⊥ lin configuration, at a frequency below the S _1/2 to P _3/2 resonance in ^40 Ca ^+ .

High-Stability Cryogenic System for Quantum Computing With Compact Packaged Ion Traps
IEEE Transactions on Quantum Engineering, 2022 Cryogenic environments benefit ion trapping experiments by offering lower motional heating rates, collision energies, and an ultrahigh vacuum (UHV) environment for maintaining long ion chains for extended periods of time.

Engineering generalized Gibbs ensembles with trapped ions
Physical Review Research, 2021 The concept of generalized Gibbs ensembles (GGEs) has been introduced to describe steady states of integrable models. Recent advances show that GGEs can also be stabilized in nearly integrable quantum systems when driven by external fields and open. Here,

Micromotion-enabled improvement of quantum logic gates with trapped ions
New Journal of Physics, 2017 The micromotion of ion crystals confined in Paul traps is usually considered an inconvenient nuisance, and is thus typically minimized in high-precision experiments such as high-fidelity quantum gates for quantum information processing (QIP).

Fast separation of two trapped ions
New Journal of Physics, 2015 We design fast protocols to separate or recombine two ions in a segmented Paul trap. By inverse engineering the time evolution of the trapping potential composed of a harmonic and a quartic term, it is possible to perform these processes in a few ...

Robust dynamical exchange cooling with trapped ions
New Journal of Physics, 2020 We investigate theoretically the possibility for robust and fast cooling of a trapped atomic ion by transient interaction with a pre-cooled ion. The transient coupling is achieved through dynamical control of the ions’ equilibrium positions.
