Intel’s Tunnel Falls: 24,000 Quantum Chips Per Wafer and the Manufacturing Argument Made Real
22 Jun 2023 - Every conversation about silicon spin qubits eventually arrives at the same claim: because these qubits are essentially single-electron transistors, they can be manufactured using the same processes that produce billions of classical transistors every year. The implication is staggering — a scalable quantum computer rolled off a semiconductor production line, not hand-assembled in a physics lab.…

Google Claims Breakthrough in Quantum Error Correction
Feb 2023 – Quantum computers hold the promise of tackling problems beyond the reach of classical machines, but they are notoriously fragile. Even tiny disturbances can introduce errors into quantum computations. To build a fault-tolerant quantum computer – one that can reliably run long computations – scientists have to keep these errors in check. Google’s Quantum AI team just reported…
