Startup Funding: November 2023


November was a banner month for quantum computing startups, with two raising rounds of $100 million for their superconducting and silicon spin qubit technology. Another significant round went to a company developing photonic-based systems. Several other companies drew funding, including one applying quantum sensors to semiconductor inspection. Sizeable funding also went to an autonomous tran... » read more

Architecting Faster Computers


To create faster computers, the industry must take a major step back and re-examine choices that were made half a century ago. One of the most likely approaches involves dropping demands for determinism, and this is being attempted in several different forms. Since the establishment of the von Neumann architecture for computers, small, incremental improvements have been made to architectures... » read more

Manufacturing Bits: May 12


Photonic thermometers The National Institute of Standards and Technology (NIST) has developed a new class of photonic thermometers. These chip-based thermometers measure temperature using light. They are resistant to electromagnetic interference and are self-calibrating. In the future, photonic thermometers could be buried into walls or sent into space. They could be used for chemical, pres... » read more
