While the AFL-CIO declares with a straight face having nearly 15 million “members”, the annual 2025 federal reporting form reveals that a full 4,823,802 of those “members” are merely Working America contacts.
More than one-third of AFL-CIO members are phantomAnd in related news
The Quantum Echoes algorithm is Google Quantum AI’s 2025 Out‑of‑Time‑Order Correlator (OTOC)–based quantum algorithm that achieves the first-ever verifiable quantum advantage, running up to 13,000× faster on the Willow quantum chip than the best classical supercomputers.
What Quantum Echoes Is
- A quantum algorithm introduced by Google Quantum AI in 2025 and published in Nature.
- It measures Out‑of‑Time‑Order Correlators (OTOCs), observables that reveal how quantum information spreads and becomes chaotic in a system.
- Unlike random circuit sampling (2019), Quantum Echoes produces verifiable expectation values—results that can be repeated and confirmed across quantum devices.
Why It Matters
- First verifiable quantum advantage: Quantum Echoes runs on Google’s 105‑qubit Willow chip and outperforms classical supercomputers by a factor of 13,000× on benchmark tasks.
- Real‑world relevance:
- Enables Hamiltonian learning and molecular structure analysis.
- Acts as a “molecular ruler” using NMR data to measure long‑range chemical distances.
- Applicable to studying molecules, magnets, and even black‑hole‑like chaotic systems.
