“…[252,253] While microwave photons in a superconducting circuit platform have been used successfully to exhibit these unconventional cavity quantum electrodynamic effects, such demonstrations are missing in the optical domain. [254] One of the principal bottlenecks faced by the topological photonics community is scalable integration of nonlinearities in the form of quantum emitters coupled to photonic cavity arrays. While the superconducting community has been successful in integrating qubits with the transmission line resonators in deterministic manner to achieve sufficiently strong nonlinearities, the photonics community, despite the inherent scalability of solid-state lattices, faces a few key challenges in similar integration of quantum emitters.…”

A key obstacle for all quantum information science and engineering platforms is their lack of scalability. The discovery of emergent quantum phenomena and their applications in active photonic quantum technologies have been dominated by work with single atoms, self-assembled quantum dots, or single solid-state defects. Unfortunately, scaling these systems to many quantum nodes remains a significant challenge. Solution-processed quantum materials are uniquely positioned to address this challenge, but the quantum properties of these materials have remained generally inferior to those of solid-state emitters or atoms. Additionally, systematic integration of solution-processed materials with dielectric nanophotonic structures has been rare compared to other solid-state systems. Recent progress in synthesis processes and nanophotonic engineering, however, has demonstrated promising results, including long coherence times of emitted single photons and deterministic integration of emitters with dielectric nano-cavities. In this review article, these recent experiments using solution-processed quantum materials and dielectric nanophotonic structures are discussed. The progress in non-classical light state generation, exciton-polaritonics for quantum simulation, and spin-physics in these materials is discussed and an outlook for this emerging research field is provided.

“…First, the photonic band-structure around the Weyl points can be modified without opening a band-gap; this enables tuning the powerlaw exponent of the interaction 1/r α , with α taking values in the interval [3/2, 3], depending on the configuration of the system. Second, this power-law behaviour is robust to certain degree of disorder in the bath, as it occurs in other topological BSs [36][37][38]. The combination of all these features in the same platform (i.e., a single platform enabling coherent, power-law, no dissipative, tunable and robust to disorder interactions between QEs) has to our knowledge never been predicted or reported in any other photonic environment.…”

“…With careful choice of laser frequencies and powers, almost arbitrary shapes of interaction forces can be synthesized [21]. In this work, we give examples of how this property could be used for quantum simulation [22][23][24][25][26][27][28][29][30], as well as for quantum computation. By designing the incoming light field, we show, for example, how the interaction between ions can be simulated, even if they are ordered in 2D or 3D geometries.…”

A Versatile Quantum Simulator for Coupled Oscillators Using a 1D Chain of Atoms Trapped near an Optical Nanofiber

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.
