Scaling Up Silicon 28 For Mainstream Silicon Qubit Chips
by Brian Wang from NextBigFuture.com on (#6ZJX7)
Transitioning to mass production of ^2Si-based spin qubit chips involves leveraging existing semiconductor infrastructure (e.g., CMOS fabs from Intel or TSMC) while addressing isotope-specific challenges. Mass production at consumer electronics levels would require capacities in the hundreds of kg to tons annually of enriched Silicon 28. Production needs to be scaled up by at least ...
