Compare our CAB interferometer to a Mach-Zehnder

A Mach-Zehnder atom interferometer can be used to measure acceleration with a T^2 scaling in sensitivity as interrogation time T is increased. We predict and experimentally measure the acceleration-sensitive phase shift of a large-momentum-transfer atom interferometer based upon Bloch oscillations. Using this novel interferometric scheme we demonstrate an improved scaling of sensitivity which will approach T^3 in the limit of large interrogation time. This enhanced scaling will allow an increase in bandwidth for acceleration-sensitive atom interferometers.
