“…• Photonic systems: These are typically linear optics systems which, combined with photon counting, may mimic a universal quantum computer, according to the famous paper from Knill, Laflamme, and Milburn [57]. Achieving strong non-linearity with photons is very challenging, but there are ongoing attempts and proposals [11]. • Twistronics systems: Twistronics deals with twisted bilayer graphene or other two-dimensional materials [26,96].…”

Contemporary quantum technologies face major difficulties in fault tolerant quantum computing with error correction, and focus instead on various shades of quantum simulation (Noisy Intermediate Scale Quantum, NISQ) devices, analogue and digital quantum simulators and quantum annealers. There is a clear need and quest for such systems that, without necessarily simulating quantum dynamics of some physical systems, can generate massive, controllable, robust, entangled, and superposition states. This will, in particular, allow the control of decoherence, enabling the use of these states for quantum communications (e.g. to achieve efficient transfer of information in a safer and quicker way), quantum metrology, sensing and diagnostics (e.g. to precisely measure phase shifts of light fields, or to diagnose quantum materials). In this Chapter we present a vision of the golden future of quantum simulators in the decades to come.

“…Due to the fact that extended Bose-Hubbard Hamiltonians are of great relevance in different physical systems [99][100][101][102][103], we expect that our results can stimulate the study of TQCPs in a broad variety of research lines. Finally, as natural extensions of the present work, we believe that the investigation of TQCPs in fermionic systems, where the extra spin degrees of freedom can give rise to interesting topological states, might represent an intriguing topic.…”

The combination of topology and quantum criticality can give rise to an exotic mix of counterintuitive effects. Here, we show that unexpected topological properties take place in a paradigmatic strongly-correlated Hamiltonian: the 1D extended Bose-Hubbard model. In particular, we reveal the presence of two distinct topological quantum critical points with localized edge states and gapless bulk excitations. Our results show that the topological critical points separate two phases, one topologically protected and the other topologically trivial, both characterized by a long-range ordered string correlation function. The long-range order persists also at the topological critical points and it reflects the presence of localized edge states protected by a finite charge gap. Finally, we introduce a super-resolution quantum gas microscopy scheme for dipolar dysprosium atoms, which provides a reliable route towards the experimental study of topological quantum critical points.

“…Correlation-based detection techniques -such as coincidence -can reveal such electromagnetic field nonlinearities. These correlations are signatures matter-induced photon-photon coupling [51], freeelectrons coupling [52] and thus carry matter information that is imprinted in the post-interaction countingstatistics. Characterization of the 'reading' process that access this information, is one of the central goals of interferometric-spectroscopy.…”

Correlated photons inspire abundance of metrology-related platforms, which benefit from quantum (anti-) correlations and outperform their classical-light counterparts. While such demonstrations mainly focus on entanglement, the role of photon exchange-phase and degree of distinguishability have not been widely utilized in quantum-enhanced applications. Using an interferometric setup we show that even at low degree entanglement, when a two-photon wave-function is coupled to matter, it is encoded with a reliable "which pathway?" information. An interferometric exchange-phase-cycling protocol is developed, which enables phase-sensitive discrimination between microscopic interaction histories (pathways). We find that quantum-light interferometry facilitates utterly different set of time-delay variables, which are unbound by uncertainty to the inverse bandwidth of the wave-packet. We illustrate our findings on an exciton model-system, and demonstrate how to probe intraband dephasing in time-domain without temporal resolution at the detection. The exotic scaling of multiphoton coincidence with respect to the applied intensity is discussed.
