QC has had its share of hype cycles. Businesses need to have a vision (which is where hype seeps in), and must be honest about what's possible today.
I am building quop.ai, a service which makes quantum computing accessible to technical and non-technical folks who don't have degrees in quantum physics.
I am not super familiar with the silicon spin, but Qutech is making progress: https://qutech.nl/2026/02/12/rolling-out-the-carpet-for-spin....
Oxford Ionics (acquired by IonQ) has a CMOS trapped ion approach: https://www.oxionics.com/blogs/unveiling-oxford-ionics-devel...
Intel is also involved in silicon spin / quantum dots with their Tunnel Falls milestone: https://quantumcomputingreport.com/argonne-national-laborato...
CalTech work is super interesting! Neutral Atoms look to be a compelling modality. QuEra and Pasqal are commercial players worth looking into.
