Topic
Design and engineering of quantum processors and the systems around them.
A Florida State group proposes holding clean solid-neon microparticles above a chip with superconducting loops, so electron qubits sit where designers put them rather than where a defect happens to be.
Reality
IBM says infrastructure, not qubit counts, stood between error-prone chips and a fault-tolerant machine. Its modular cryostats and 1-metre superconducting cables are the commitment behind the 2029 date.
Reality
The trapped-ion roadmap has now delivered 32, 56 and 98 qubits in consecutive generations. What matters next is whether ion transport through junctions keeps scaling.
Reality
The trapped-ion company signed a joint development deal with contract manufacturer Quanta Computer for hardware infrastructure. No new processor, no volumes, no timetable, and that is the tell.
