Coherent Feedback Cooling of an Ultracoherent Phononic-Crystal Membrane at Room Temperature
Luiz Couto Correa Pinto Filho, Yingxuan Chen, Frederik Werner Isaksen +6
Optomechanical systems provide a versatile platform for precision measurements and investigations of fundamental physics, where bringing macroscopic resonators into the quantum reg…
Quantifying Effective Heterodyne Detection Efficiency with SI-Traceable Standards
Luiz Couto Correa Pinto Filho, Jesper B. Christensen, Anders Brusch +1
Accurate calibration of coherent optical receivers is essential for reliable performance assessment in coherent communications, precision and quantum sensing, and continuous-variab…
Mitigating nonlinear transduction noise in high-cooperativity cavity optomechanics
Daniel Allepuz-Requena, Zohran Ali, Dennis Høj +4
Coupling mechanical motion to an optical resonator enables displacement measurements approaching the standard quantum limit (SQL). However, increasing the optomechanical coupling s…
Squeezing light with optomechanical and spin-light quantum interfaces
Gian-Luca Schmid, Manel Bosch Aguilera, Chun Tat Ngai +6
We investigate squeezing of light through quantum-noise-limited interactions with two different material systems: an ultracold atomic spin ensemble and a micromechanical membrane.…
