We propose a terahertz continuous-variable quantum key distribution protocol using pulse position modulation, which enables simultaneous quantum and classical communication for inter-satellite links.

Abstract: This presents a low-power, high-data-rate impulse-radio ultra-wideband (IR-UWB) transmitter that integrates a two-dimensional differential pulse position modulation (2D-DPPM) with ...

Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

If you have a brain, and if you know others who do, then you know there’s a catastrophic catalogue of ways that our skull-socket electro-fat computers can disappoint their owners. From memory-loss to ...

Astronomers are puzzled, and that’s putting it mildly. A strange pattern of pulses, repeating like clockwork, has been detected from 3I/ATLAS, an interstellar object cruising through our Solar System.

Developed a novel photo-memristor with single-pulse low energy consumption (187 pJ) and multi-pulse linearity up to 0.996. Using photoelectric synaptic characteristics, achieved long-term memory in a ...
