Lattice gauge theories, which originated from particle physics in the context of Quantum
Chromodynamics (QCD), provide an important intellectual stimulus to further develop …

We present a brief overview of some of the analytic perturbative techniques for the
computation of the Floquet Hamiltonian for a periodically driven, or Floquet, quantum many …

A large qubit capacity and an individual readout capability are two crucial requirements for
large-scale quantum computing and simulation. As one of the leading physical platforms for …

The concept of “Floquet engineering” relies on an external periodic drive to realize novel,
effectively static Hamiltonians. This technique is being explored in experimental platforms …

We present a topological approach to the input-output relations of photonic driven-
dissipative systems acting as directional amplifiers. Our theory relies on a mapping from the …

The quantum system under periodical modulation is the simplest path to understand the
quantum nonequilibrium system because it can be well described by the effective static …

An ion‐lattice quantum processor based on a two‐dimensional arrangement of linear
surface traps is presented. The design features a tunable coupling between ions in adjacent …

We present a simple quantum theory of a bosonic trimer in a triangular configuration, subject
to gain and loss in an open quantum systems approach. Importantly, the coupling constants …

A rich and powerful toolbox for individually trapped atomic ions is available for quantum
information processing, including quantum metrology and quantum simulation …

We investigate a scalable trapped-ion array architecture for quantum control of many
particles, extending techniques to access multiple dimensions. Our experimental study …
