DESCRIPTION:Atom interferometry is a novel quantum sensing technology base
 d on the principles of quantum mechanics and the wavelike nature of ultrac
 old atoms. Matter-wave physics has rapidly developed since the days of de 
 Broglie with the theory and demonstration of Bose-Einstein condensation in
  laboratories to the manipulation of such cold atom systems for quantum si
 mulation\, quantum computing\, and matter-wave interferometry. These new t
 echnologies are now at a stage where they are leaving the confines of extr
 emely clean laboratory environments and moving out into the field to be de
 ployed as gravimeters\, gradiometers\, and long-baseline detectors. At the
  10 m scale atom fountains have demonstrated high sensitivity to accelerat
 ions\, measurements of the rotation of the earth\, tests of the Equivalenc
 e Principle and large scale tests of quantum mechanics by separating and d
 etecting a superposition of rubidium atoms at a distance of 54 cm. We now 
 look to scale these types of detectors up to the 100 m and 1 km baseline l
 ength\, and eventually move the technology to space. By utilizing advances
  in atom interferometry such as: large momentum transfer\, gradiometry\, a
 nd atomic clock modes of strontium we aim to advance these detectors to a 
 stage capable of searching for ultralight dark matter and as a new testbed
  for gravitational wave searches in the mid-frequency band (0.3 Hz — 5 H
 z). I will present some background on atom interferometers and how we look
  to build these long-baseline devices at the MAGIS-100 experiment at Fermi
 lab in the US and the AION project in the UK and what a future network of 
 these devices could look like. I will then discuss the current status\, se
 nsitivities\, and technological challenges and terrestrial limitations for
  these long-baseline atom interferometers. \n\nJoin Zoom Meeting\nhttps://
