Testing and evaluation is how serious science moves forward. Microsoft’s topological quantum system is now on site in Maryland, where DARPA will put the hardware through its paces. Here’s why that matters for the path to quantum at scale:

Testing the whole machining job before the first chip! 💻 Second thing that stayed with me from the @Siemens plant in Chemnitz. Offline simulation for machining is not new. What's different here is what gets virtualized. Siemens builds a digital twin of the CNC control as well as the machine, so the program runs against a virtual SINUMERIK rather than an approximation of one. That's why the workflow actually holds together. Programming, simulation and validation sit in one environment, and once a process is validated virtually, the same program goes to the real machine. → Machining programs tested virtually before anything moves → Process behaviour analysed and collisions caught before the first physical run → The validated program transfers straight into production → The MTR is controlled by SINUMERIK ONE and programmed in G-code, so the digital and physical sides speak the same language This matters more for a robot than for a conventional machine tool. Robots are being pushed into steel milling and large-part machining, where the parts are expensive, the setups are awkward, and a crash is not a cheap lesson. First-time-right stops being a nice goal and becomes the condition for using the technology at all. Robotics gives you the flexibility, the CNC gives you the control, and the digital twin is what makes the first cut the right one. ~~  ♻️ Join the weekly robotics newsletter, and never miss any news →

Testing the assignee dropdown in @planepowers. I asked Grok for dummy data and avatars to test it. It built a flight software crew. Stacked selections, search, clear checkmarks, and those tiny faces. A lot of care for one dropdown, exactly how we like it.
