Breakthrough in room-temperature quantum coherence reported
A result worth taking seriously and a long way from a machine, the coherence times are real, and still six orders of magnitude short of useful.

Opening of Breakthrough in room-temperature quantum coherence reported
The finding is genuine and the paper is careful. Coherence at room temperature removes one of the more expensive constraints on quantum hardware, and if it replicates it is a meaningful step.
It is not a computer. The demonstrated coherence times remain far below what error correction requires, the system involves a small number of qubits, and nothing about the result addresses the scaling problems that dominate the field.
