Single-photon detectors with picosecond timing resolution have advanced rapidly in the past
decade. This has spurred progress in time-correlated single-photon counting applications …

The production of pairs of entangled photons simply by focusing a laser beam onto a crystal
with a nonlinear optical response was used to test quantum mechanics and to open new …

This article creatively proposes a class of sorting matrices with fractal characteristics, named
the fractal sorting matrix (FSM), and introduces its iterative calculation method. The FSM is …

We present a 1 Mpixel single-photon avalanche diode camera featuring 3.8 ns time gating
and 24 kfps frame rate, fabricated in 180 nm CMOS image sensor technology. We designed …

Attosecond science has demonstrated that electrons can be controlled on the sub-cycle time
scale of an optical waveform, paving the way towards optical frequency electronics …

The demand to process vast amounts of data generated from state-of-the-art high resolution
cameras has motivated novel energy-efficient on-device AI solutions. Visual data in such …

High-resolution single-photon imaging remains a big challenge due to the complex
hardware manufacturing craft and noise disturbances. Here, we introduce deep learning into …

Radiographic imaging and tomography (RadIT), which started with Röntgen's seminal X-ray
work in 1895, now includes an increasing number of IT modalities. In addition to the original …

Lidar has already achieved long-distance and high-accuracy detection due to the improved
sensitivity and timing accuracy of single-photon detectors (SPDs). However, single-photon …

Robust object detection under photon-limited conditions is crucial for applications such as
night vision, surveillance, and microscopy, where the number of photons per pixel is low due …
