This method exploits a Floquet engineering scheme that allows the identification of optimal quantum transport. In particular, I will address how this approach effectively integrates various techniques of large momentum transfer atom optics, ranging from adiabatic manipulations (such as Bloch-type ac-celeration) to highly non-adiabatic regimes involving Bragg pulses. In addition, the Floquet scheme allows for optimal state-to-state control in large Hilbert spaces, surpassing the capabilities of traditional brute-force numerical methods. Using this method, we have experimentally achieved very efficient coherent acceleration of cold atoms, with an efficiency greater than 0.9995 per photon recoil (hk). We have also demonstrated atom interferometers with an unprecedented momentum separation of 6007k between the two arms of the interferometer [1].<br>I will further discuss the potential of this approach to support interferometers with momentum separations well beyond 1000hk, opening new opportunities for applications in precision metrology and quantum technologies. In particular, this development addresses a critical challenge for the realization of very large scale atom interferometers, which are crucial for future gravitational wave detection and new fundamental tests.<\/p>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/wp-content\/uploads\/2024\/08\/GAUGUET-ALEXANDRE-optimal-floquet-engineering-for-large-scale-atom-interferometers-1.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"Embed of GAUGUET ALEXANDRE optimal floquet engineering for large scale atom interferometers.\"><\/object><a id=\"wp-block-file--media-b64d2603-73bf-4c08-ab17-118b660d63e9\" href=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/wp-content\/uploads\/2024\/08\/GAUGUET-ALEXANDRE-optimal-floquet-engineering-for-large-scale-atom-interferometers-1.pdf\">GAUGUET ALEXANDRE optimal floquet engineering for large scale atom interferometers<\/a><a href=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/wp-content\/uploads\/2024\/08\/GAUGUET-ALEXANDRE-optimal-floquet-engineering-for-large-scale-atom-interferometers-1.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-b64d2603-73bf-4c08-ab17-118b660d63e9\">Download<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Video Presentation Abstract We have introduced a novel approach to matter-wave optics based on the stroboscopic stabilization of quantum states within an accelerated optical lattice [1].
