HSPs are crucial in various quantum technologies. The utilization of a heralded single-photon (HSP), as opposed to a classical light source, enables superior sensitivity in quantum sensing applications. This investigation focuses on the successful generating HSPs to design a highly sensitive quantum optical temperature sensor. The HSPs were produced from a PPKTP nonlinear crystal using the spontaneous parametric down-conversion process (SPDC) under the quasi-phase matching (QPM) condition. The signal and idler photons resulting from this process were transmitted through two different identical optical fibers and then to two identical single-photon detectors. The temporal properties of these photons were analyzed using a coincidence counter. A portion of the fiber carrying the signal was decladded to serve as the sensor probe. The sensor was calibrated by measuring the average transmittance with varying temperatures near the sensor probe. The sensing principle is explained deriving an expression for average transmittance as a function of temperature. The measurement error surpassed the Standard Quantum Limit (SQL), improving measurement sensitivity. The resolution and sensitivity of the developed quantum sensor were shown to be 0.0925 °C and 0.00677 /°C respectively. This study emphasizes the potential for enhancing sensitivity and minimizing shot noise with the use of HSPs. The merits of the proposed sensor, over the other quantum senor is its less complex design and low decoherence.</div></div>","PeriodicalId":19586,"journal":{"name":"Optics Communications","volume":"591 ","pages":"Article 132176"},"PeriodicalIF":2.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the bicubic interpolation method is introduced to enhance the resolution of sea surface modeling. Secondly, the sea surface height difference iteration method (SSHIM) is proposed to calculate photon refraction points rapidly. Based on these advances, this study proposes an innovative path loss simulation method based on the grid cell collective photon refraction (GCCPR) method. The proposed method is verified in three simulation scenarios: sea surface energy distribution, receiving plane energy distribution and received optical power (ROP). The highest Pearson correlation coefficient between the proposed method and MC simulation is 89.62 % for the receiving plane energy distribution, and the calculation speed of the proposed method can be more than 1000 times faster than the MC simulation. Finally, the feasibility of the proposed method is validated through experiments with regular and irregular two-dimensional (2D) waves.
