Silicon spin gains manufacturing evidence while demonstrated scale stays small

July brought integrated cryogenic control and new process-development commitments. HRL's chip can host 18 qubits, but its largest published circuit used seven.

SaxonQ tells SCN a demo SXQ128 is in setup, with first 8-qubit coupled-NV delivery due this quarter

In written responses, CEO Marius Grundmann says the cores are not entangled and details the estimates behind SaxonQ's six-to-ten-times energy claim.

The Switch That Doesn't Collapse the Qubit

Cisco's research prototype and DARPA's 19-team backbone program together define what the first-generation network layer of a quantum-classical hybrid actually looks like, and what still doesn't work.

EU Launches SPINS Quantum Pilot Line to Manufacture Spin Qubit Chips

Led by imec and backed by the Chips Joint Undertaking, SPINS aims to prove that semiconductor fabs, not research labs, are where quantum computing finally scales. Ten countries and three silicon platforms, all betting on spin.
