Diraq, an Australian company, is advancing quantum computing by producing qubit devices with over 99% fidelity using CMOS technology, as detailed in a Nature article. This industrial process enables the creation of small evaluation devices that could pave the way for larger functional qubit systems. Some reports suggest these devices may align with DARPA's Quantum Benchmark Initiative goals, although specific documentation from DARPA on these goals is not readily available. The discussion highlights the significance of Diraq's work in the context of quantum technology development. Overall, Diraq's innovations could play a crucial role in the future of quantum computing.

TL;DR
Diraq's qubits chips hold up 99+% accuracy when made in an industrial CMOS foundry.
The Nature article "Industry-compatible silicon spin-qubit unit cells exceeding 99% fidelity" describes an industrial process used by the Australian company "Diraq" to manufacture small (2 qubit) evaluation devices using CMOS technology.

The results show that the process will likely support much larger functional qubit devices.

Some articles (such as this one from Science Daily) also claim that the study demonstrates the devices will meet DARPA's Quantum Benchmark Initiative (QBI) goals, but I cannot find any DARPA document describing any such goals.

Thread 'Another trick with Blender using geometry nodes'

After playing around a bit with making star maps, I found another video which introduced me to another trick that can be done using geometry nodes. This one involves fluids. For background, Blender has a fluid physics simulator, which, as the name suggests simulates the behavior of fluids. What this person did was to use geometry nodes to convert the fluid into a point cloud. Then he added a turbulence force field to "stir it around". He was then able to extract the velocity information...

Thread 'Is AI Overhyped?'

In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...

Thread 'Windows 10 Now Not Supported'

Well, the date has now passed, and Windows 10 is no longer supported. Hopefully, the readers of this forum have done one of the many ways this issue can be handled. If not, do a YouTube search and a smorgasbord of solutions will be returned. What I want to mention is that I chose to use a debloated Windows from a debloater. There are many available options, e.g., Chris Titus Utilities (I used a product called Velotic, which also features AI to prevent your computer from overheating etc...
