In this paper, we propose using optical-controlled uniform circular frequency diverse array (UCFDA) to generate orbital angular momentum (OAM) beams. Simulation experiments are conducted, and impact ...

Single-Photon Avalanche Diodes (SPADs) are an emerging pixel technology able to detect the arrival of single photons. Arrays of SPADs can be used to image a scene in binary frames, indicating whether ...

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate.
