The statistical error in any estimation can be reduced by repeating the measurement and averaging the results. The central limit theorem implies that the reduction is proportional to the square root of the number of repetitions. Quantum metrology is the use of quantum techniques such as entanglement...
Advances in Quantum Metrology with Dielectrically Structured Single Photon Sources Based on Molecules In the realm of fundamental quantum science and technologies, non‐classical states of light, such as single‐photon Fock states, are widely studied. Howev... P Lombardi,H Georgieva,F Hirt,... -...
Quantum sensing has become a broad field. It is generally related with the idea of using quantum resources to boost the performance of a number of practical tasks, including the radar-like detection of faint objects, the readout of information from optic
Since its discovery, quantum entanglement has challenged some of the best established views of the world: locality and reality. Quantum technologies promise to revolutionize computation, communication, metrology and imaging. Here we review conceptual and experimental advances in complex entangled systems ...

Speckle metrology includes various optical techniques that are based on the speckle fields generated by reflection from a rough surface or by transmission through a rough diffuser. These techniques have proven to be very useful in testing different materials in a non-destructive way. They have change...
Connecting to a SQUID results in a highly sensitive current detector. The device is a candidate for closing the quantum metrology triangle (QMT) experiment, a long-standing goal in metrology. The aim of the QMT is to improve confidence in the planned revision of the SI unit system by ...
Quantum Efficiency Advances Sensors for Night Vision In recent years, low-noise CMOS imaging sensors have triggered many new opportunities and applications for the night-vision market. Although low noise is key, it is not the only parameter to consider when dealing with low-light vision. ...
Key factors in the impact of particle deposition on photovoltaic resources. 光伏资源评估的总体流程如图2所示。为接收到更多的太阳辐射,光伏组件通常倾斜安装(赵争鸣等, 2005),所以在第一步中,在通过数值模式或再分析资料得到地表太阳辐照度分布后,需考虑安装倾角、方位角等因素,利用倾斜表面总辐照度估算模型(Maleki...
