DOI: 10.1103/2crh-5yvr
Abstract: We design a phase-sensitive Rydberg-atom interferometry by implementing Floquet electromagnetically induced transparency (FEIT). The FEIT mixes the sidebands of a Rydberg state induced by a MHz radio frequency (RF) field and recombines them into FEIT… 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.
