Fast Generation of Metrologically Relevant Fock State Mixtures
Gonzalo Reina Rivero, Marcel Morillas-Rozas, Alberto López-García +1
We propose a fast laser pulse sequence for the generation of non-thermal Fock state mixtures of the motion of a trapped ion, targeted at displacement metrology beyond the standard…
Critical Sensing with Autonomous Devices: The Self-Oscillation Threshold of a Frequency-Locked NV-Centre Magnetometer
Joan Toledo Aguilera, Gonzalo Reina Rivero, Marcel Morillas-Rozas +1
Feedback locking of a probe frequency to a spin resonance is the standard operating mode of precision quantum sensors. Here we deliberately operate such a lock outside its stable r…
Dark Polaron Theory for High Intensity Laser Cooling
Marcel Morillas-Rozas, Alberto López-García, Enamul Haque +2
Conventional laser control schemes for cooling and gate operation of trapped ions are limited to the regime of weak laser intensities and small Lamb-Dicke parameters. To overcome t…
