Three Nobel Prizes in quantum and atom optics (1997, 2001 and 2005) have paved the way and motivated EuroQUASAR.  These achievements have contributed to the development of methods to cool and trap atoms with laser light; achievement of Bose-Einstein condensation in dilute gases of alkali atoms; and, development of laser-based precision spectroscopy, including optical frequency comb technique.  “Quantum standard” stands for future optical clocks, inertial sensors of unprecedented precision and novel fundamental tests based on atomic, molecular or mesoscopic quantum systems with well defined, unique and eternal features.  EuroQUASAR projects will contribute to:

• Quantum-Degenerate Gases for Precision Measurements
• Inertiam Atomic and Photonic Quantum Sensors: Ultimate Performance and Application
• Molecule Interferometry and Metrology
