Quantum mechanics is at the heart of our technology and economy - the laser and the transistor are quantum devices - but its full potential is far from being realized. Recent technological advances in optics, nanoscience and engineering allow experimentalists to create artificial structures or put microscopic and mesoscopic systems under new manipulable conditions in which quantum phenomena play a fundamental role.

Quantum technologies exploit these effects with practical purposes. The objective of Quantum Science is to discover, study, and control quantum efects at a fundamental level. These are two sides of a virtuous circle: new technologies lead to the discovery and study of new phenomena that will lead to new technologies.

Our aim is  to control and understand quantum phenomena in a multidisciplinary intersection of  Quantum Information, Quantum optics and cold atoms, Quantum Control, Spintronics, Quantum metrology, Atom interferometry, Superconducting qubits and Circuit QED and Foundations of Quantum Mechanics.

QUINST is funded in part as a “Grupo Consolidado” from the Basque Government (IT472-10, IT986-16, IT1470-22)  and functions as a network of groups with their own funding, structure, and specific goals.

Title: Quantum Integrability and the Rabi model


The Rabi model is  the simplest quantum system containing two interacting degrees of freedom. Although it does not possess a conserved quantity besides the energy, it is integrable and can therefore e exactly solved for all parameter values. To this end the classical concept of integrability has to be extended to the quantum domain where systems with few discrete levels couple continuous (radiation) degrees of freedom. A new criterion for quantum integrability is proposed. It turns out that a non-integrable generalization of the Rabi model can be exactly solved as well.
