The growing maturity of nanofabrication has ushered massive sophisticated optical
structures available on a photonic chip. The integration of subwavelength-structured …

Since the pioneering works by Landau, Zener, Stückelberg, and Majorana (LZSM), it has
been known that driving a quantum two-level system results in tunneling between its states …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Simulating quantum mechanics is known to be a difficult computational problem, especially
when dealing with large systems. However, this difficulty may be overcome by using some …

Designing future‐proof materials goes beyond a quest for the best. The next generation of
materials needs to be adaptive, multipurpose, and tunable. This is not possible by following …

Metamaterials, artificial electromagnetic media that are structured on the subwavelength
scale, were initially suggested for the negative-index'superlens'. Later metamaterials …

We propose tunable chiral bound states in a system composed of superconducting giant
atoms and a Josephson photonic-crystal waveguide (PCW), with no analog in other …

Quantum computing and simulations are creating transformative opportunities by exploiting
the principles of quantum mechanics in new ways to generate and process information. It is …

This Colloquium presents an overview of the research on nonlinear electromagnetic
metamaterials. The developed theoretical approaches and experimental designs are …

Quantum simulators are controllable quantum systems that can be used to simulate other
quantum systems. Being able to tackle problems that are intractable on classical computers …
