| 1 | 坐标测量系统的几何误差补偿(英文)显示文摘坐标测量系统(CMSs)的软件补偿由于能以很低的价格,显著地改善系统性能而获得广泛的应用.即使对于已经建立了完善模型方程的坐标测量系统,仍然存在与其相适配的确定模型参数的过程是否最佳的问题.在更差的情况下,模型方程尚未建立,需要从建模到试验的全部实践.文中从补偿过程的角度讨论这一问题,确定了需要遵循的一系列步骤.对于每一步骤,指出了相关的问题,并提出建议.讨论了两种在性质和数学描述上有很大差别的坐标测量系统. | Alessandro Balsamo Alice Meda | 2006 | 纳米技术与精密工程2006，4，2： | 5 |
| 2 | Realization of the first sub-shot-noise wide field microscope显示文摘Recently,several proof of principle experiments have demonstrated the advantages of quantum technologies over classical schemes.The present challenge is to surpass the limits of proof of principle demonstrations to approach real applications.This letter presents such an achievement in the field of quantum enhanced imaging.In particular,we describe the realization of a sub-shot-noise wide field microscope based on spatially multi-mode non-classical photon number correlations in twin beams.The microscope produces realtime images of 8000 pixels at full resolution,for a 500μm2 field of view,with noise reduced to 80%of the shot noise level(for each pixel),which is suitable for absorption imaging of complex structures.By fast post-elaboration,specifically applying a quantum enhanced median filter,the noise can be further reduced(to o30%of the shot noise level)by setting a trade-off with the resolution,thus achieving the best sensitivity per incident photon reported in absorption microscopy. | Nigam Samantaray Ivano Ruo-Berchera Alice Meda Marco Genovese | 2017 | Light(Science & Applications)2017，6，1： | 3 |
| 3 | Quantifying backflash radiation to prevent zero-error attacks in quantum key distribution显示文摘Single-photon avalanche diodes(SPADs)are the most widespread commercial solution for single-photon counting in quantum key distribution applications.However,the secondary photon emission that arises from the avalanche of charge carriers that occurs during the detection of a photon may be exploited by an eavesdropper to gain information without inducing errors in the transmission key.In this paper,we characterize such backflash light in gated InGaAs/InP SPADs and discuss its spectral and temporal characterization for different detector models and different operating parameters.We qualitatively bound the maximum information leakage due to backflash light and propose solutions for preventing such leakage. | Alice Meda Ivo Pietro Degiovanni Alberto Tosi Zhiliang Yuan Giorgio Brida Marco Genovese | 2016 | Light(Science & Applications)2016，5，1： | 0 |
