  1. Feb 16, 2024The Rydberg blockade mechanism is an important ingredient in quantum simulators based on neutral atom arrays. It enables the emergence of a rich variety of quantum phases of matter, such as topological spin liquids. The typically isotropic nature of the blockade effect, however, restricts the range of natively accessible models and quantum states. In this work, we propose a method to ...

    Jan 9, 2025Neutral atom analog quantum hardware excels in simulating large and complex systems, but its utility remains restricted by the specific class of problems that can be naturally encoded in such devices. This work extends the concept of Rydberg gadgets---clusters of atoms whose joint dynamics give rise to enhanced computational capabilities---beyond their original use in quantum optimization to ...

    dimer model. Note that a single-dimer flipping term could exist in finite-size systems with one narrow direction, such as the clusters in Fig.S1(b,e). FIG. S4. Example of non-trivial diagonal processes in the triangular gadget model. In these processes, one edge dimer can be created after removing two nearby gadget atoms.
  6. Diluted dimer models with Rydberg gadgets. - We now specify the Rydberg gadget models depicted in Fig.1(c-f). We consider the square and triangular lattices, with a Rydberg atom on each edge, and a gadget on each vertex. The gadgets consist of 4 or 6 atoms on the square and triangular lattices, respectively. Edge and gadget atoms are ...

    This is a decisive step towards the realization of a quantum simulator with circular Rydberg atoms. In this work, the circular Rydberg atoms were trapped but unorganized, as the particle of a gas would do in a closed box. ... Together with Ignacio Cirac, you have developed a model of a quantum computer as early as in 1995. If you had been asked ...

    During PASQuanS2.1, we will set the basis for this full software stack, implementing first versions already for specific quantum simulations. Development of digital twins Validation, verification, and benchmarking of quantum simulators will benefit strongly from the development of machine-specific digital models, which map the system-specific ...
