Moreover, thanks to their state-of-the-art methods of fabrication, they may now enter regimes of non-linear interactions between their constituent mechanical and optical degrees of freedom. In this work, we show how this novel opportunity may serve to construct a new generation of optomechanical sensors. We consider the canonical optomechanical setup with the detection scheme being based on time-resolved counting of photons leaking from the cavity. By performing simulations and resorting to Bayesian inference, we demonstrate that the non-classical correlations of the detected photons may crucially enhance the sensor performance in real time. We believe that our work may stimulate a new direction in the design of such devices, while our methods apply also to other platforms exploiting non-linear light-matter interactions and photon detection.<\/jats:p>","DOI":"10.22331\/q-2022-09-20-812","type":"journal-article","created":{"date-parts":[[2022,9,20]],"date-time":"2022-09-20T11:22:36Z","timestamp":1663672956000},"page":"812","update-policy":"http:\/\/dx.doi.org\/10.22331\/q-crossmark-policy-page","source":"Crossref","is-referenced-by-count":5,"title":["Exploiting non-linear effects in optomechanical sensors with continuous photon-counting"],"prefix":"10.22331","volume":"6","author":[{"given":"Lewis A.","family":"Clark","sequence":"first","affiliation":[{"name":"Centre for Quantum Optical Technologies, Centre of New Technologies, University of Warsaw, Banacha 2c, 02-097 Warszawa, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bartosz","family":"Markowicz","sequence":"additional","affiliation":[{"name":"Centre for Quantum Optical Technologies, Centre of New Technologies, University of Warsaw, Banacha 2c, 02-097 Warszawa, Poland"},{"name":"Faculty of Physics, University of Warsaw, Pasteura 5, 02-093 Warszawa, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Ko\u0142ody\u0144ski","sequence":"additional","affiliation":[{"name":"Centre for Quantum Optical Technologies, Centre of New Technologies, University of Warsaw, Banacha 2c, 02-097 Warszawa, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"9598","published-online":{"date-parts":[[2022,9,20]]},"reference":[{"key":"0","doi-asserted-by":"publisher","unstructured":"C.
