Today's lead: an IBM/Qedma/RIKEN/BlueQubit quantum magnetism result gets cross-validated on Quantinuum's rival hardware, raising the bar for what counts as a durable quantum advantage claim. Plus: IonQ's 256-qubit chip samples, a Chicago community fight over a $9B quantum campus, Nvidia's classical-compute bet, a dense new qubit proposal, and India's new quantum foundry.

Today's episode digs into a New Scientist feature revisiting Sergey Frolov's Science paper on failed Majorana zero-mode replications — physics central to Microsoft's Topological Core roadmap — plus four quick hits spanning benchmark rigor, single-pulse qubit gates, altermagnetic spintronics, and prethermal plateau theory.

This week a KAIST team showed that bound entanglement — real, provable quantum correlation that can't be distilled into clean entangled pairs — can't deliver the exponential learning speedup the quantum machine learning field has long attributed to entanglement generically. This Sunday think piece walks the full fault line: the KAIST result itself, the Huang-Kueng-Preskill and ancilla-qubit camps defending real exponential advantages, the 2018 dequantization tradition that keeps eating QML's boldest claims, and the Schuld/Killoran and Aaronson objections to the whole 'quantum beats classical' framing.
