High-Performance Ultrafast Lasers That Fit on a Fingertip

New high-performance ultrafast lasers are being made on nanophotonic chips. The new work centers on miniaturizing mode-lock lasers — a unique laser that emits a train of ultrashort, coherent light pulses in femtosecond intervals, which is an astonishing quadrillionth of a second. Ultrafast mode-locked lasers are indispensable to unlocking the secrets of the fastest timescales …

ColdQuanta Atom Tech for Million Qubit Quantum Computers and Beyond

ColdQuanta cools atoms to a few millionths of a degree above absolute zero and uses lasers to arrange the atoms, hold them in place, run computations on them, and read out the results. Quantum calculations, communications, and sensing are the result. Satyendra Bose and Albert Einstein discovered the fifth form of matter—the Bose-Einstein Condensate (BEC). …

SpaceX Starlink Can Provide Super GPS With a Software Modification

There is an arxiv paper “Fused Low-Earth-Orbit GNSS”, by Peter A. Iannucci and Todd E. Humphreys of the Radionavigation Laboratory, The University of Texas at Austin, that details how low-earth orbit satellites can be modified to provide super-precise GPS. MIT Technology Review indicates that the system would be accurate to 70 centimeters. Simple software upgrades …

Amazon and China Belt and Road delay profits and building logistics

Amazon has posted just a handful of profitable quarters in its two-decade history and now has a $550 billion valuation. “Bezos’ ability to paint an extraordinary vision (i.e., ‘Earth’s Biggest Store’) and register steady progress against that vision is rewarded with the cheapest capital in the history of business,” says Galloway. “And… Cheap. Capital. Is. …
