How to Build a Quantum Supercomputer
summary
Claims a concrete full-stack path: liftoff-free junctions made by deposition-and-etch with SiO2 scaffolds already yielding tens of microseconds, a wafer-scale plan that tiles 20,000 qubits per wafer and routes signals with 100,000 superconducting wires to a 3 K cryo-electronics layer, a microwave-photon readout mapped to a switching device showing about ~1% readout error, and a cost target around $100M versus multibillion alternatives, with Applied Materials tooling and thermal-conductivity tests underway.
