Quantum clocks built from randomness offer a new perspective on time, merging quantum mechanics with timekeeping and ...

New device emits photons in telecom fiber band from the start, so it avoids a separate converter that can waste photons.

Nuclear security specialist Sébastien Philippe, one of the 22 recipients of this year's prestigious MacArthur fellowship, ...

Dating dinosaur eggs is difficult: available methods are limited and prone to errors because measurement proxies – such as volcanic rocks or crystals – may have changed between egg laying and dating ...

Abstract: We report on measurements of frequency shifts in a microwave cesium vapor cell atomic clock based on coherent population trapping (CPT). The dependence of the clock frequency on numerous ...

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But ...

A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the University of Warsaw has developed ...

How the IEEE P-1952 standard categorizes five levels of resilience for PNT user equipment. Understanding GNSS Disciplined Oscillators. How Alternative PNT represents a new frontier in timing ...

MIT physicists improved the stability of optical atomic clocks by reducing “quantum noise” — a fundamental measurement ...

Better yet, modern hypervisors can run most of the popular operating systems inside VMs – including FreeBSD distros and even Hackintosh setups. However, my home lab primarily utilizes Linux-based ...

Abstract: Low-frequency radio astronomy is essential for studying astrophysical phenomena such as solar activity, pulsar emissions, and the 21-cm signal. This paper presents a newly developed ...
