DOI: 10.1103/2ym8-vs82
Abstract: Assembling increasingly larger-scale defect-free optical-tweezer-trapped atom arrays is essential for quantum computation and quantum simulations based on atoms. Here, we propose an AI-enabled, rapid, constant-time-overhead rearrangement protocol, and we experimentally assemble defect-free 2D and 3D… read more here.

DOI: 10.1103/dpn8-63p6
Abstract: Rydberg atom arrays promise high-fidelity quantum simulations of critical phenomena with flexible geometries. Yet experimental realizations inevitably suffer from disorder due to random displacements of atoms, leading to departures from the expected behavior. Here, we… read more here.

DOI: 10.1103/jz4d-vdhj
Abstract: Non-stabilizer states are a fundamental resource for universal quantum computation. However,despite broad significance in quantum computing, the emergence of"many-body"non-stabilizerness in interacting quantum systems remains poorly understood due to its analytical intractability. Here we show that… read more here.

DOI: 10.1103/physrevlett.134.213604
Abstract: Locality is a transversal principle that governs quantum dynamics of many-body systems. However, for cavity-embedded systems, such a fundamental notion is hindered by the presence of nonlocal cavity modes, leaving space for new possible dynamical… read more here.
