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

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

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 …

The efficiency of the future devices for quantum information processing is limited mostly by
the finite decoherence rates of the individual qubits and quantum gates. Recently …

Abstract In circuit quantum electrodynamics,,,,,,,,,(QED), where superconducting artificial
atoms are coupled to on-chip cavities, the exploration of fundamental quantum physics in …

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

Enhancing optical nonlinearities so that they become appreciable on the single photon level
and lead to nonclassical light fields has been a central objective in quantum optics for many …

Photon blockade is a dynamical quantum-nonlinear effect in driven systems with an
anharmonic energy ladder. For a single atom strongly coupled to an optical cavity, we show …

We present a combined analytical and numerical study for coherent terahertz control of a
single molecular polariton, formed by strongly coupling two rotational states of a molecule …

An as yet outstanding goal in quantum optics is the realization of fast optical nonlinearities at
the single-photon level. This would allow for the implementation of optical devices with new …
