Quantum Litmus — The Daily Reality Check for Quantum Computing
Independent, evidence-first analysis of what changed in quantum computing today, why it matters, and what the evidence does not yet show.
A new grid study finds that quantum speedup can disappear when the full calculation is counted.
Better measurement of usefulness today, but no improvement in broad quantum-computing readiness.

In plain English
A quantum computer might perform the mathematical core of a grid calculation efficiently, but loading the grid data and extracting all the answers can consume the supposed advantage.
