Realization of an All-Optical Effective Negative-Mass Oscillator for Coherent Quantum Noise Cancellation
Abstract
We report the realization of an all-optical, tabletop effective negative-mass oscillator (ENMO) scheme capable of canceling quantum noise when cascaded with an optomechanical sensor susceptible to (quantum) radiation pressure noise. Our coherent quantum noise cancellation (CQNC) scheme offers a broadband cancellation capability with a tunable, wavelength-flexible, and compact system. This is achieved through the implementation of an optical equivalent of an optomechanical interaction, facilitated by a down-conversion and a beam-splitting process [Tsang and Caves, Phys. Rev. Lett. 105, 1 (2010)]. The intricate nature of the system and its multiple interacting components made characterizing the interdependent parameters with conventional methods ineffective, leading to the development of an in situ characterization scheme. The obtained parameters meet the targets for CQNC set in previous studies [Wimmer et al., Phys. Rev. A: At. Mol. Opt. Phys. 89, 053836 (2014)]. With our current realization, we project a broadband quantum noise reduction of 3.6 dB, corresponding to a 77% reduction in quantum back-action noise at the optimal frequency of maximum reduction, indicating the readiness of the ENMO for application. We discuss the prospects for new applications in quantum information and communication using the same platform.
