Lawrence Livermore’s National Labs National Ignition Facility compressed microscopic copper samples with pressures of 30 million atmospheres to triple the density of copper. This created the densest object on the planet for a brief moment in time. They used diamond …
Scientists at Stanford and SLAC have created a silicon chip that can accelerate electrons using an infrared laser to deliver, in less than a hairs width, the sort of energy boost that takes microwaves many feet. Above – This image, …
Weak and strong gravitational fields can be produced by a single continuously circulating unidirectional beam of light. In the weak gravitational field of a unidirectional ring laser, it is predicted that a spinning neutral particle, when placed in the ring, …
Silicon is a compelling platform for classical optical telecommunications as well as quantum communications, both through optical fibers. In general, the silicon-based integrated quantum transceivers could provide possible low-cost and high-performance secure communication networks. A reliable transfer of single photon …
General Fusion has successfully closed USD$65 million with a Series E round led by Temasek (Singapore fund). There was US$38 million (C$50 million) released from the Canadas Strategic Innovation Fund. The total funds recently made available to General Fusion is …
Researchers at the University of Warwick and University of Oxford have developed a new way to simulate quantum systems of many particles, that allows for the investigation of the dynamic properties of quantum systems fully coupled to slowly moving ions. …
This article has information from the quantum computer expert John Preskill. We are going to get more and better quality qubits with lower error rates. The overhead cost for error correction improves as gate error rate declines. The Google Quantum …
HZDR (German) scientists are investigating whether controlled fusion could be facilitated with the assistance of tunneling processes using radiation But that is also a question of energy: the lower it is, the lesser the likelihood of tunneling. Conventional laser radiation …
Commonwealth Fusion Systems (CFS), a startup commercializing fusion energy, has raised $115 million and closed its Series A round. New participants in the round include Future Ventures, Khosla Ventures, Lowercase Capital, Moore Strategic Ventures, Safar Partners, Schooner Capital, and Starlight …
The Mach Effect Propulsion NASA NIAC study went through a lot of effort to prove there was no vibration generated errors. The entire presentation and most of the Q&A was a defense of the validity of the first test device. …
