As it has been demonstrated that trapped ion systems have unmatched long-lived quantum-bit (qubit) coherence and can support high-fidelity quantum manipulations, how to scale up the system size becomes an inevitable task for practical purposes. In this work, we theoretically analyse the physical limitation of scalability with a trapped ion array, and propose a feasible scheme of architecture that in principle allows an arbitrary number of ion qubits, for which the overhead only scales linearly… 
Scalable and parallel tweezer gates for quantum computing with long ion strings
TLDR
The inherent scalability of this approach is demonstrated by presenting analytical and numerical results for long 1D ion chains and even for infinite chains of uniformly spaced ions, and it is shown that combining the methods with optimal coherent control techniques allows to realize maximally dense universal parallelized quantum circuits.

Fast quantum logic gates with trapped-ion qubits
TLDR
This work demonstrates entanglement generation for gate times as short as 480 nanoseconds—less than a single oscillation period of an ion in the trap and eight orders of magnitude shorter than the memory coherence time measured in similar calcium-43 hyperfine qubits.

TLDR
This work shows how to achieve massively parallel gate operation in a large-scale quantum computer, based on techniques already demonstrated for manipulating small quantum registers, and uses the use of decoherence-free subspaces to do so.

TLDR
It is shown that a two-dimensional “crystal” of around 200 9Be+ ions held together by magnetic and electric fields in a so-called Penning trap can simulate quantum magnetism, which sets the stage for simulations with more complicated forms of interaction that classical computers would find intractable.
