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.

IBM Discloses $10 Billion Quantum Investment Plan as 2029 Fault-Tolerance Target Comes Into Focus

IBM told investors it plans to spend more than $10 billion on quantum over five years. Annualized, that is roughly twice the U.S. federal QIS R&D budget, but the figure is a blended forward-looking plan, not a booked balance-sheet item.

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.
