Result description
This work provides a robust, feedback-based cooling strategy that uses phase-sensitive control to reach sub-quantum occupation in mechanical oscillators. By optimizing the modulation parameters, the scheme remains effective even with moderate losses and timing errors. It offers a practical pathway to quantum ground-state preparation in levitated optomechanics and related systems.
We present an optimized protocol that combines phase-preserving measurements with parametric modulation at resonance to cool a quantum oscillator below one phonon in steady state. The method determines the ideal modulation phase and duration, and remains effective under realistic dissipation and feedback imperfections. This result is relevant for researchers working on quantum control of levitated mechanical systems and advancing ground-state cooling techniques.
