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 …

Superconducting circuits based on Josephson junctions exhibit macroscopic quantum
coherence and can behave like artificial atoms. Recent technological advances have made …

A transition between energy levels at an avoided crossing is known as a Landau–Zener
transition. When a two-level system (TLS) is subject to periodic driving with sufficiently large …

The observation of the quantum states of motion of a macroscopic mechanical structure
remains an open challenge in quantum-state preparation and measurement. One approach …

We investigate the effective interaction between two microwave fields, mediated by a
transmon-type superconducting artificial atom which is strongly coupled to a coplanar …

We review the physical phenomena that arise when quantum mechanical energy levels are
modulated in time. The dynamics resulting from changes in the transition frequency is a …

We study optically driven Rabi rotations of a quantum dot exciton transition between 5 and
50 K, and for pulse areas of up to 14 π. In a high driving field regime, the decay of the Rabi …

A strong photon-photon nonlinear interaction is a necessary condition for a photon
blockade. Moreover, this nonlinearity can also result in a bistable behavior in the cavity field …

Quantum two-level systems interacting with the surroundings are ubiquitous in nature. The
interaction suppresses quantum coherence and forces the system towards a steady state …
