About QUINST

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 group's 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.

Title: Detection of quantum entanglement
Abstract
There have been many experiments recently that produced various entangled quantum states with cold trapped ions, photons, cold atomic ensembles, etc. It is an important step in these experiments to verify the presence of entanglement and to obtain information on the fidelity of the quantum state observed with respect to the state we wanted to prepare. This is a challenge since a many-body quantum system has very many degrees of freedom, thus a complete quantum tomography is not possible. Practically useful methods are based on entanglement conditions that need few local measurements.
