With hybridization we have a quantum and classical sensor measuring acceleration with respect to a joint inertial reference therefore enabling common mode noise rejection. We have used a novel opto-mechanical resonator in order to suppress the effects of inertial noise coupling in our atom interferometer. The OMR possesses a very small form factor, therefore apart from eradicating the need to use a vibration isolation system it also allows for compact dimensions of the sensor head. Therefore, considering the complimentary benefits of the quantum sensor and OMR we foresee the potential for a highly sensitive, portable, compact and robust hybrid quantum inertial navigation sensor.
