Commercial quantum sensors using atom interferometry and laser sources for precision metrology

M Squared is developing quantum sensors for quantum gravimetry and inertial navigation. Using atom interferometry, each promises performance advantages over their classical counterparts. Each system is designed for use in the challenging operational environment of a moving platform, and incorporates active systems that compensate for the effects of environmental noise. Each sensor is presented along with a performance evaluation in laboratory settings and in field trials. An account is also given on how M Squared laser systems are being used to enable some of the world’s most advanced precision metrology experiments.
