Modelling wavefunction collapse as a continuous flow yields insights on the nature of measurement

Quantum coin flip: In quantum mechanics, wavefunction collapse is traditionally regarded as an instantaneous event, but quantum state diffusion treats it as a gradual process, like a coin that wobbles ...

Function-Reused Oscillator-PA for IoT Applications

Abstract: To realize an energy-efficient transmitter (TX) for ultra-low-power (ULP) Internet-of-Things (IoT) applications, function-reuse oscillator–power-amplifiers (Osc-PAs) provide high efficiency ...
