Argonne Couples Traveling Spin Waves to Superconducting Circuits
The hybrid experiment demonstrates direction-dependent microwave transmission. Its 4-decibel isolation result also shows why qubit-level protection remains a separate test.

Chemistry Offers a Smaller Model for Diamond Qubit Candidates
A molecular-cluster approach to computational materials screening narrows the search, but candidate defects still need their quantum behavior tested.
AWS’s Quantum-Resistant Signing Guide Shows Where Policy Stops
The October 12 deployment guides connect keys, identities and software verification, while leaving application-level cryptography outside cloud API controls.
Post-selected error correction | Tools for Quantum Advantage | Ep4
Qiskit explains how parity checks, stabilizer measurements and combinations of checks can flag suspect quantum-computing runs so they can be discarded. The lesson introduces post-selection, with useful context for understanding error-correction research. The important trade-off is that rejecting runs reduces the number of usable samples; this is an error-detection approach, not a demonstration of full fault-tolerant computation or quantum advantage.
