Quantum key distribution using quantum dot single-photon emitting diodes in the red and near infrared spectral range [PDF]

, 2012
We report on in-lab free space quantum key distribution (QKD) experiments over 40 cm distance using highly efficient electrically driven quantum dot single-photon sources emitting in the red as well as near-infrared spectral range.

Overcoming phonon-induced dephasing for indistinguishable photon sources [PDF]

, 2012
Reliable single photon sources constitute the basis of schemes for quantum communication and measurement based quantum computing. Solid state single photon sources based on quantum dots are convenient and versatile but the electronic transitions that ...

Evaluation of Single Photon and waveform LiDAR

, 2019
In this talk, the principles of single photon sensitive LiDAR are presented and compared against state-of-the-art full waveform, linear-mode LiDAR. The differences are explained in theory, and data of either technology are evaluated based on the City of

High-Flux Fast Photon-Counting 3D Imaging Based on Empirical Depth Error Correction

Photonics, 2023
The time-correlated single-photon-counting (TCSPC) three-dimensional (3D) imaging lidar system has broad application prospects in the field of low-light 3D imaging because of its single-photon detection sensitivity and picoseconds temporal resolution ...

Multiscale Feature Fusion for the Multistage Denoising of Airborne Single Photon LiDAR

Remote Sensing, 2023
Compared with the existing modes of LiDAR, single-photon LiDAR (SPL) can acquire terrain data more efficiently. However, influenced by the photon-sensitive detectors, the collected point cloud data contain a large number of noisy points.

Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media

Advanced Science, EarlyView.
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

Open‐Shell Conjugated Polymers Enable Photothermoelectric Conversion and Detection of Short‐Wave Infrared Light

Advanced Science, EarlyView.
Efficient conversion and detection of short‐wave infrared (SWIR) photons are becoming increasingly important for emerging photonic and energy technologies. Here, we report an organic photothermoelectric device based on an open‐shell conjugated polymer that enables SWIR energy conversion and photon detection via the photothermoelectric effect.
