The current understanding of the role of topology in non-Hermitian (NH) systems and its far-
reaching physical consequences observable in a range of dissipative settings are reviewed …

Quantum information is vulnerable to environmental noise and experimental imperfections,
hindering the reliability of practical quantum information processors. Therefore, quantum …

Full manipulation of a quantum system requires controlled evolution generated by nonlinear
interactions, which is coherent when the rate of nonlinearity is large compared with the rate …

In non-Hermitian crystals showing the non-Hermitian skin effect, ordinary Bloch band theory
and Bloch topological invariants fail to correctly predict energy spectra, topological boundary …

We report the experimental detection of bulk topological invariants in nonunitary discrete-
time quantum walks with single photons. The nonunitarity of the quantum dynamics is …

We propose to directly and quantum-coherently couple a superconducting transmon qubit to
magnons—the quanta of the collective spin excitations, in a nearby magnetic particle. The …

Superconducting circuits have emerged as a powerful platform of quantum simulation,
especially for emulating the dynamics of quantum many-body systems, because of their …

We present and analyze a method where parametric (two-photon) driving of a cavity is used
to exponentially enhance the light-matter coupling in a generic cavity QED setup, with time …

Periodically driven systems have displayed a variety of fascinating phenomena without
analogies in static systems, which enrich the classification of quantum phases of matter and …

We study chiral models in one spatial dimension, both static and periodically driven. We
demonstrate that their topological properties may be read out through the long time limit of a …
