“Really sloppy” Semiconductor Manufacturing Won’t Suffice in Quantum Computing’s Development

“Really sloppy” Semiconductor Manufacturing Won’t Suffice in Quantum Computing’s Development Interesting commentary. Though provided by a manufacturer of atomically precise manufacturing (APM) equipment, anyone with a background in solid-state devices will find truth to what is being stated. Cleaning up the semiconductor processes should go […]

Limits of Quantum Communication Networks; Secret Key Capacity Explored

Limits of Quantum Communication Networks; Secret Key Capacity Explored Establishing the ultimate limits of quantum communication networks At the moment, sensitive data is typically encrypted and then sent across fibre-optic cables and other channels together with the digital “keys” needed to decode the information. However, […]

Promising Research into Nanofabricating Fake Atoms Shows Promise in Quantum-secure Communications, Computing

University of Oregon, Center for Optical, Molecular, and Quantum Science.  Ultra-secure online communications, completely indecipherable if intercepted, are a step closer with the help of a recently published discovery by University of Oregon physicist Ben Alemán. Alemán, a member of the UO’s Center for Optical, […]
