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: Localization of electron-hole complexes in quantum semiconductorstructures

Semiconductor nanostructures such as quantum wells and quantum wires contain inevitable interface roughnesses at the interfaces, which strongly affect optically excited electron-hole complexes, including excitons and trions. The effect of localization of these complexes at fluctuations of quantum well width or quantum wire radius is studied by the variational method. The efficient and physically justified trial functions are suggested. Their applicability is illustrated for some model cases, a brief comparison with available experimental data is carried out.
