“…Due to the collisional blockade effect [18,19] , at most, one atom can be located for each optical lattice site. The strong coupling between the trapped atomic array and fiber-guided mode contributes to the study of chiral quantum optics [20] , collective excitation [21] , and correlating photons under nonlinear response [22] . Using electromagnetically induced transparency, slow light and the storage of optical pulses are also realized in the nanofiber optical lattice [23,24] .…”

“…As photons within the fiber propagate over practically infinite distances, they collectively couple to all atoms, which induces all-to-all long-range interactions [11]. In this way thousands of atoms can be trapped, which leads to strong collective effects [12].…”

The transversely confined propagating light modes of a nanophotonic optical waveguide or nanofiber can effectively mediate infinite-range forces. We show that for a linear chain of particles trapped within the waveguide’s evanescent field, transverse illumination with a suitable set of laser frequencies should allow the implementation of a coupled-oscillator quantum simulator with time-dependent and widely controllable all-to-all interactions. Using the example of the energy spectrum of oscillators with simulated Coulomb interactions, we show that different effective coupling geometries can be emulated with high precision by proper choice of laser illumination conditions. Similarly, basic quantum gates can be selectively implemented between arbitrarily chosen pairs of oscillators in the energy as well as in the coherent-state basis. Key properties of the system dynamics and states can be monitored continuously by analysis of the out-coupled fiber fields.

“…The platforms for WQED include natural atoms, quantum defects, superconducting qubits [1][2][3]. The WQED setup can be harnessed to generate and detect quantum light [4], for slow light and quantum memory applications [5] and as a simulator of many-body quantum physics [6,7]. The unique features of the WQED problem include strong non-Hermiticity due to the escape of photons into the waveguide, that can be both super-and sub-radiant and long-ranged waveguide-mediated interactions between the atoms.…”

Arrays of atoms coupled to photons, propagating in a waveguide, are now actively studied due to their prospects for generation and detection of quantum light. Quantum simulators based on waveguides with long-range couplings were also predicted to manifest unusual many-body quantum states. However, quantum tomography for large arrays with N > 20 atoms remains elusive since it requires independent access to every atom. Here, we present a novel concept for analogue quantum simulations by mapping the setup of waveguide quantum electrodynamics to the classical problem of an electromagnetic wave, propagating in a wire metamaterial. By experimentally measuring the near electromagnetic field we emulate the localization arising from polariton-polariton interactions in the quantum problem. Our results demonstrate the potential of wire metamaterials to visualize quantum light-matter coupling in a table-top experiment and may be applied to emulate other exotic quantum effects, such as quantum chaos, and self-induced topological states.
