The post-measurement pairing in MP-QKD alleviates the photon-coincidence demands, which are essential for surpassing the fundamental limit to the key-rate transmission. In this work, we propose an improved decoy-state MP-QKD protocol featuring a flexible and efficient pairing strategy. We prove the security of the proposed scheme by presenting an entanglement model for decoy-state MP-QKD. The simulation results show that the secret key rate (SKR) can be enhanced among all distances. Notably, compared with the original scheme [Nature Communication13, 3903 (2022)10.1038/s41467-022-31534-7], the improvement of SKR is greater than 65% within 375 km in the asymptotic case and greater than 50% within 400 km in the finite case. And the achievable distance can be extended in the finite case, especially with a small block length. The simulation results demonstrate the high efficiency of the proposed scheme, which is expected to promote the practical applicability of MP-QKD. Furthermore, the entanglement model could provide a theoretical framework for further security and performance analysis of decoy-state MP-QKD.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 11","pages":"23939-23959"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144294602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Using unidimensional single-quadrature encoding, we suggest alignment of the measurement bases relying on the asymmetry of the phase-space distribution of the modulated states. By rotating the bases so that the maximum quadrature variance is observed, the remote communicating party can identify the signal quadrature direction. Depending on the coherence time of the signal and the repetition rate of the system, the necessary statistics can be accumulated to minimize misalignment between the preparation and measurement bases. We address the issue of residual bases misalignment in the suggested shared-reference-frame-independent continuous-variable quantum key distribution protocol and show that it is feasible with state-of-the-art techniques. The result paves the way for low-cost and simplified quantum communication schemes, which are independent of any shared phase reference and are therefore immune to potential quantum hacking attacks on the local oscillator or pilot tones.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 11","pages":"22643-22653"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144294605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Traditional interferometry systems face significant design challenges when dealing with high energies, large fields of view, and short lengths, such as those required for full-body CT scans. DBAs offer a solution to these issues by generating intensity fringes through the superposition of diffracted and transmitted beamlets, rather than relying on interference. This innovative approach allows for independent variation of the diffraction angle and fringe period, decoupling the fringe formation distance from the design energy. As a result, it is possible to construct imaging systems comparable to Talbot-Lau interferometers with a more flexible parameter space. This flexibility enables shorter system designs, interchangeable design energies, and larger source grating pitches. The advantages of DBAs are demonstrated with a simulation study for the design of a chest X-ray dark-field CT, where traditional Talbot-Lau systems would require grating parameters that are currently impractical to manufacture.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 11","pages":"23835-23849"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144294608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

However, it is quite challenging at a long distance for far-field macroscopic Fourier ptychography (FP). In this work, we present what we believe to be a novel illumination scheme for macroscopic FP using a spatial light modulator to programmatically modulate the coherent illumination light, which could provide flexible and accurate angle-varied illumination at a relatively long distance. Compared with the existing macroscopic FP illumination methods, it does not need any bulky mechanism to drive laser scanning, thus improving data collection efficiency, and it can also freely adjust the illumination spot size through phase coding to avoid the issues of limited field of view and excessive dispersion of illumination energy. Finally, the illumination scheme is combined with a single camera to form a new solid-state macro FP approach, which is validated experimentally through various everyday objects and USAF targets at lab-scale range. The experimental results confirm its suitability and effectiveness for macro FP imaging.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 11","pages":"24060-24071"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144294613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

In particular, it is the enabling technology to record extremely fast luminous signals with accuracy down to a few picoseconds. However, setup limits like the presence of pile-up and dead-time-related phenomena impose a strong limitation to the speed of TCSPC experiments. In particular, the average number of recorded events is typically limited below 0.05 photons per excitation period, and also in those cases where the sample can emit a significantly higher photon rate. Many efforts have been done in the past few years to maximize speed, including the design of fast detectors and associated electronics, with nanosecond and sub-nanosecond dead time and multi-hit capabilities. Moreover, new advanced techniques have been proposed to get rid of distortion phenomena, thus enabling unprecedented speed. The goal of this paper is to provide a deep understanding of the ultimate limits to measurement speed, considering the best solutions presented so far. A general step-by-step methodology is proposed to calculate maximum speed in different conditions and to select the best suited technology to push speed to the edge depending on specific operation cases.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 11","pages":"22270-22295"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144294617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
