We have demonstrated transport of {sup 9}Be{sup +}ions through a two-dimensional Paul-trap array that incorporates an X junction, while maintaining the ions near the motional ground state of the confining potential well. We expand on the first report of the experiment in Blakestad et al.[Phys. Rev. Lett. 102, 153002 (2009)], including a detailed discussion of how the transport potentials were calculated. Two main mechanisms that caused motional excitation during transport are explained, along…

Generation of large coherent states by bang–bang control of a trapped-ion oscillator
TLDR
Here, bang–bang control of a trapped-ion oscillator is demonstrated using nanosecond switching of the trapping potentials, which provides new possibilities for quantum-state manipulation and generation, alongside the potential for a significant increase in operational clock speed for trapped-ions quantum information processing.
Arrays of individually controlled ions suitable for two-dimensional quantum simulations
TLDR
This work demonstrates individual control of the electronic and motional degrees of freedom, preparation of a fiducial initial state with ion motion close to the ground state, as well as a tuning of couplings between ions within experimental sequences, paves the way towards a quantum simulator of two-dimensional systems designed at will.
Multi-element logic gates for trapped-ion qubits

An entangling quantum gate between ions of different elements which can serve as an important building block of QIP, quantum networking, precision spectroscopy, metrology, and quantum simulation is demonstrated.
Micromotion-enabled improvement of quantum logic gates with trapped ions
The micromotion of ion crystals confined in Paul traps is usually considered an inconvenient nuisance, and is thus typically minimised in high-precision experiments such as high-fidelity quantum
