“…The metasurface consisted of domino-like nanostructured elements (nanoantennae) that supported the electrical dipole resonance at the pump wavelength of 3.95 μm. The conversion efficiency was enhanced by the metasurface resonance to the degree that it even allowed the single-shot measurements avoiding damage to the material, thus providing the possibility to study the controllable transition between the perturbative and non-perturbative regimes of light-matter interactions at the nanoscale depending on the pumping conditions [88].…”

“…To reduce the many wired electrical interconnections which have long been considered a reliability problem, a source of unwanted noise, and a huge area requirement for conventional wire bonding pads, threedimensional (3D) wafer-scale ion traps based on 88 Sr + were fabricated in a CMOS-compatible process [26] The use of electrically conducting through-silicon vias (TSVs) has resulted in higher performance Q-factor, high power spectral density, and lower insertion loss. TSVs and CMOS packaging methods have resulted in a 95% area reduction.…”

The materials challenge is often a major hurdle for translating good ideas in science into technologies. This is no different in the arena of quantum technologies which has seen a resurgence of interest in the last decade. This perspective provides a unique insight into the recent collaborative works by research groups in Singapore to surmount key quantum materials and processing bottlenecks that have impeded quantum technologies in the areas of sensing, computing, and communications. We highlight recent important materials related breakthroughs that have made possible novel advancements such as integrated ion traps, light frequency conversion, highly efficient cryogenic contacts to atomically thin quantum devices, and gate defined quantum dots, to name just a few. We also discuss the potential applications and conclude with our perspective on the remaining challenges to be addressed and the prospects enabled by these materials advances for future collaborations and co-developments to advance quantum technologies.

“…Eq. ( 3) is typically assumed valid also for time-varying resonant structures, as done for example in [32], [33], [34], [35], [37]. In this context, however, it is important to note that in a time-varying optical system, conservation of energy within the system is broken since time-translation symmetry (time invariance) is locally broken [38] (the term γext(t) in Eq.…”

Trapping and storing light for arbitrary time lengths in open cavities is a major goal of nanophotonics, with potential applications ranging from energy harvesting to optical information processing. Unfortunately, however, the resonance lifetime of conventional open resonators remains finite even in the limit of vanishing material absorption, as a result of radiation loss. In this context, bound states in the continuum (BiCs) have provided a unique way to achieve unbounded resonance lifetimes despite the presence of compatible radiation channels. However, physical constraints such as reciprocity, linearity, and delaybandwidth limits prevent the possibility to externally excite such ideal bound states and make them interact with broadband sources. Here, we overcome these limitations and theoretically demonstrate that subwavelength open resonators undergoing a suitable temporal modulation can efficiently capture a broadband incident wave into a nonradiating eigenmode of the structure, leading to the first example of a BiC that is accessible to broadband light. Our findings unveil the dynamic capabilities of bound states in the continuum and extend their reach and potential impact for different applications.

“…and the quantities V k α and Z k αβ are exactly those used to construct the incident field vector and impedance matrix within the MoM matrix equation ( 21) at frequency ω k = ω c + kω 0 . We recognize the above expression as a generalization of the multi-port network relation (16), where now the time-varying elements are allowed to relate currents and voltages across multiple ports. Adapting the notation of ( 17), (18b), and (19), we arrive at the conversion matrix system…”

A conversion matrix approach to solving network problems involving time-varying circuit components is applied to the method of moments for electromagnetic scattering analysis. Detailed formulations of this technique's application to the scattering analysis of structures loaded with time-varying circuit networks or constructed from general time-varying media are presented. The computational cost of the method is discussed, along with an analysis of compression techniques capable of significantly reducing computational cost for partially loaded systems. Several numerical examples demonstrate the capabilities of the technique along with its validation against conventional methods of modeling time-varying electromagnetic systems, such as finite difference time domain and transient circuit co-simulation.
