Abstract
The endeavour to control increasingly larger systems of particles at the quantum level is a natural goal, and will be a driving force for the physical sciences in the coming decades. The control of a many-body system at the highest level possible can indeed be regarded as the ultimate form of engineering. Within this general research avenue, building quantum simulators and performing experimental quantum simulations will play a key role. A quantum simulator is a promising candidate to become the first application of quantum information science reaching beyond classical limitations [], since the requirements on the number of quantum particles and fidelities of operations are predicted to be substantially relaxed compared to that envisioned for a universal quantum computer. This issue forms an extensive open-access resource spanning the various areas of experimental quantum simulation, from its relation to quantum information processing to its potential use for different applications.

A quantum simulator is a promising candidate to become the first application of quantum information science reaching beyond classical limitations [1], since the requirements on the number of quantum particles and fidelities of operations are predicted to be substantially relaxed compared to that envisioned for a universal quantum computer
This issue forms an extensive open-access resource spanning the various areas of experimental quantum simulation, from its relation to quantum information processing to its potential use for different applications
The contributions can be broadly aligned with three research fields within the topic of quantum simulation: (i) complex many-body physics, such as quantum spin systems in condensed matter physics, (ii) transport phenomena and (iii) relativistic physics
Summary
The strategy of quantum simulations here is to experimentally initialize the quantum spin system in a state that can still be accurately prepared and to subsequently evolve the system adiabatically by changing its parameters to reach a new state, for example, via a quantum phase transition—a state that is fundamentally or, at least, currently impossible to create otherwise. In [25], the authors from Sandia National Laboratories demonstrate their design, fabrication and experimental implementation of micro-fabricated radio-frequency (rf) surface electrode traps, as depicted in figure 1. Their scheme is suitable to advance the multiplex architecture of interconnected linear traps, featuring a scheme of many memory and processor traps, housing sub-ensembles of ions and spanning the architecture for a universal quantum computer. For this purpose, their contributed experimental show case already incorporates a junction of three linear traps (see left part of figure 1). In [14], the authors present an optimization process to potentially reduce the technological efforts based on a single rf-electrode, providing an optimal lattice geometry for maximizing the ratio of coupling strength between the ions and the motional heating rates causing decoherence
