Waveguide QED (WQED) platforms allow a strong coupling regime and promises several essential applications in quantum science and technology. Due to the nature of infinite-range and photon-mediated dipole-dipole interactions in WQED systems, quantum dynamics simulations of atomic excitations showcase intriguing collective behaviors, where excitation trapping effect emerges and many-body dark states can be formed. Lastly, I will share our recent progress in the state carving technique, where unit probability of generating Bell states can be feasible by using one photon interacting with the atoms twice, without the need of high cooperativity in the atom-cavity interface. Efficient state-carving paves the way for large-scale entanglement generation at cavity-interfaces for modular quantum computing, quantum repeaters and creating arbitrary shaped atomic graph states, essential for one-way quantum computing.
