TL;DR: In this paper, the authors demonstrate a universal qudit quantum processor using trapped ions with a local Hilbert space dimension of up to 7. With a performance similar to qubit quantum processors, this approach enables native simulation of highdimensional quantum systems, as well as more efficient implementation of qubit-based algorithms.

TL;DR: In this paper, a fault-tolerant universal set of gates on two logical qubits in a trapped-ion quantum computer is demonstrated, where the absence or presence of dangerous errors is heralded by usage of few ancillary 'flag' qubits.

TL;DR: In this paper, a 19-inch rack quantum computing demonstrator based on a linear Paul trap is presented to address the challenges of scaling up system sizes or allowing for applications outside of laboratory-grade environments.

TL;DR: Cycle benchmarking as discussed by the authors is a rigorous and practically scalable protocol for characterizing local and global errors across multi-qubit quantum processors, including cross-talk and other correlated noise sources.
