Microsoft team behind the recent breakthrough in physics and quantum computing demonstrated by the new Majorana 1 chip, engineered from an entirely new material that has the potential to scale to millions of qubits on a single chip. Microsoft today introduced Majorana 1, the world’s first quantum chip powered by a new Topological Core architecture …
Centrifugal Magnetic Mirrors could enable commercial nuclear fusion reactors on Earth and are also promising for next level propulsion in space. There is funded near term work for both goals. An early Centrifugal Magnetic Mirror propulsion concept could achieve 1 to 10 newtons of thrust with 10,000 to 30000 ISP. This would be propulsion that …
High Temperature Superconductor (HTS) wires must be be better than copper wire on price-performance metrics before copper can be widely replaced. A HTS wire segment shows the energy density properties that are five to ten times better than commercial HTS wire. It will need to be scaled up to the hundreds of tons of production …
A startup, Cutting Edge Superconductors, claims to have a variant of the South Korean LK99 room temperature superconductor that shows low resistance and some weak evidence of meissner effect and quantum locking. The sample is tiny. They are trying to get a few hundred thousand in SBIR and NASA grants and $600,000 in crowdfunding. The …
China’s room temperature superconductor research continues. Here is the latest published work from the team from multiple universities and labs. This is the same teams that found stronger magnetic indications of Meissner effect in LK99 variant materials. Through heavily doping sulfur into an apatite framework, chinese researchers synthesized a new blend mainly comprising variant apatite …
SCTL has retracted the claimed full levitation video and the claim of full levitation. They say it was from the Lorentz force. A lone researcher on the team fooled himself and uploaded the video without checking with other members of the team. SCT lab : “I apologize for causing confusion. The last video of sample …
New video from SCTL Korea room temperature superconductor experimenters claimed to shows a very strong full levitation effect. Full levitation would be evidence of the Meissner effect found only in superconductors. I have shown how the levitation evidence was originally partial levitation. Critics says partial levitation can be from diamagnetics or even some iron contamination. …
Investigation of the zero resistance and temperature-dependent superconductivity phase transition in Pb-Cu-P-S-O compound by Huk Geol Kim, Dae Cheol Jeong and Hyun-Tak Kim. Hyun-Tak Kim is one of the lead researchers for the LK99 team. This new paper presents a specific critical temperature for PCPOSOS, demonstrating consistency with the original authors’ data. In this study, …
The performance of superconducting microwave circuits is strongly influenced by the material properties of the superconducting film and substrate. While progress has been made in understanding the importance of surface preparation and the effect of surface oxides, the complex effect of superconductor film structure on microwave losses is not yet fully understood. In this study, …
Chinese researchers have published a new non-peer reviewed paper on their sulfur copper doped led apatite room temperature superconductor. They have increased the Meissner effect signal. Supplemental material from the China researchers. This describes the precise work done show they did not make measurement errors. Background Context In mid-2023, the Original Korean researchers discovered the …
SCT Lab published a paper on how they make the Pb-Cu-P-S-O compound that has some pieces with potential room temperature superconductivity. The description of the process to make it is partial. How they get the powders is not described. They did not give mass ratios (cited intellectual property). The testing process for zero resistivity did …
