• Abstract: A variety of physical platforms are investigated for quantum control of many particles, and techniques are extended to access multiple dimensions. Here, we present our experimental study of shuttling single Mg$^+$ ions within a scalable trap-array architecture that contains up to thirteen trapping sites in a three-dimensional arrangement. We shuttle ions from a dedicated loading hub to multiple sites with a success rate of larger than $0.99999$. In a prototype application, we demonstrate the preservation of the coherence of superposition states of a hyperfine qubit during inter-site shuttling. Our findings highlight the potential of these techniques for use in future large-scale architectures.

  We show that Penning traps can be used to realize remarkably clean bilayer crystals, wherein hundreds of ions self-organize into two well-defined layers. These bilayer crystals are made possible by the inclusion of an anharmonic trapping potential. We illustrate that it may be possible to extend the ideas presented here to realize multilayer crystals with more than two layers.

  We show control and single-shot readout of qudits with up to 13 computational states. This represents more than twice as many computational states per qudit compared with prior work in trapped ions. We anticipate efficiently utilizing available energy states in a trapped ion to play a significant and complementary role in scaling up the computational space of a trapped ion quantum computer.

  We study three key pillars in multi-pod systolic array designs, namely array granularity, interconnect, and tiling. We identify optimal array granularity across workloads and show that state-of-the-art commercial accelerators use suboptimal array sizes for single-tenancy workloads. We propose Scale-out Sy Arrays, a multi-pod inference accelerator for both single- and multi-tenancy.

  Generation and control of quantum correlations in high-dimensional systems is a major challenge in the present landscape of quantum technologies. We propose a protocol that is able to attain entangled states of $d$-dimensional systems through a quantum-walk-based it transfer & accumulate mechanism. In particular, we illustrate a possible photonic implementation where the information is encoded in the orbital angular momentum and polarization degrees of freedom of single photons.

We demonstrate that the large number of magnetic sublevels leads to distinct bulk and edge behaviors.
