@GiaShi3 @skdh The race is between physics fixes (topological qubits, cleaner materials) and engineering hacks (decoupling, error correction, cryogenics). I’m most excited about materials that cut decoherence at the source — that’s where quantum goes from fragile to scalable.

[Ruben Zack @RuvymZack]

@luigi_maroni @skdh This isn’t about opinions, it’s physics. The second you manipulate atoms, coherence starts dying. That’s why billion-dollar labs run at near absolute zero with insane error correction just to keep a few qubits alive for microseconds.Without coherence, there is no quantum computer

The genius of Plato's Academy was that it functioned as a talent magnet and "think tank." It became a sort of political consultancy.

Its main product was not ideas or texts but the network itself: a concentration of the smartest individuals in the region, who would spread Plato's influence for generations to come.

Plato's eventual preeminence was not due to the quality of his ideas per se but his production of high-quality students.

This is shown empirically in Randall Collins’ extraordinary book The Sociology of Philosophies: Plato beat the others because he enjoyed the greatest out-degree centrality (students) and eigenvector centrality (students weighted by quality, e.g. Aristotle).

When I teach Principal Component Analysis (PCA), I start with the core idea: a linear, orthogonal transformation that maximizes variance and removes correlation.

Then we jump into my interactive, hands-on demo — using a #Python dashboard built with @matplotlib to perform PCA step by step! 📊🧠

New Record: 6,100 Qubits With Neutral Atoms

Researchers at CalTech have successfully trapped more than 6,100 atoms with laser “tweezers” in a 2D array, and kept them coherent for more than 12 seconds. These trapped atoms can function as the computational units of quantum computers, the qubits, and in this business 12 seconds counts as remarkably long.

The researchers also managed to and moved the atoms around without messing up the stored information, which will come in useful for error correction. Neural Atoms have been a latecomer in the race for commercially useful quantum computers but have been catching up dramatically fast in the past years. Still what is missing is a demonstration that they can create entanglement and perform logical operators on the arrays at scale. Paper here. Press release here.

A measurement of the collective Lamb shift in a one-dimensional array of 30 dysprosium atoms shows how dipole interactions shift the resonance in both low- and high-excitation regimes, linking linear optics and Ramsey spectroscopy results.

Fuse is re-writing the renewables playbook from sunbeam to socket. There are countless new retail energy outfits around the world, but none matches Fuse's ambition when it comes to managing electrons. @Lowercarbon is proud to back them again.

Display fridges emit as much CO₂ as 2M cars.
And they drain 500 TWh of electricity every year — the same as Germany’s total power use.
The invisible monster hiding in plain sight.
