In 2019, researchers from Shanghai Jiao Tong University in China developed a new method called correlation on spatially-mapped photon-level image (COSPLI), which allows for mapping and measuring large-scale photonic quantum correlations with single-photon sensitivity. The COSPLI technique can detect signals from single photons and their correlations in tens of millions of images, making it a versatile solution for performing quantum particle measurements in large-scale photonic systems.
Mapping and Measuring Photonic Quantum Correlations
The COSPLI method enables researchers to map and measure large-scale photonic quantum correlations with single-photon sensitivity. This technique allows the detection of signals from individual photons and their correlations across tens of millions of images, making it a powerful tool for performing quantum particle measurements in complex photonic systems.
Advantages of COSPLI
The COSPLI technique offers several key advantages:
– **Single-Photon Sensitivity**: The method can detect signals from individual photons, enabling the study of quantum-level phenomena.
– **Large-Scale Mapping**: COSPLI can analyze tens of millions of images, allowing for the mapping of large-scale photonic quantum correlations.
– **Versatility**: The technique can be applied to a wide range of photonic systems, making it a valuable tool for quantum research and applications.
