Quantum Enhanced Atom Interferometer

Development and optimization of high-performance quantum sensors is an important aspect of quantum research with a broad range of technological applications including gravimetry and field gradiometry, and fundamental applications such as gravitational wave detection. Atom interferometers are a class of quantum sensors that utilize coherent manipulation of momentum states of matter waves to measure various forces on atoms. Improving the sensitivity of previously demonstrated guided matter-wave atom interferometer is of key importance. We are working towards demonstrating the improvements in sensitivity of such an atom interferometer over the standard quantum limit via quantum entangled momentum states of atoms. We will use an initial twin Fock position state in a double-well trap to create a twin Fock momentum state through selective application of momentum transfer with flexible and dynamic optical potentials. Utilizing single atom detection in our double well potential will facilitate the creation of such twin Fock state, ultimately allowing us to demonstrate a quantum-enhanced atom interferometer. The current progress towards this project will be discussed here.
