found a *fantastic* new (to me) resource today - MIT's #Quantum Index Report, and specifically the benchmarking section. Covers all the major hardware modalities, with graphs on adoption, timelines, market share, qubit count, fidelity, error rate over time, coherence, and much more. I'll be coming back to this a lot in the months and years ahead. qir.mit.edu/benchmarking/

QIR - Quantum Index Report · Insights – Quantum Processor Benchmarking - QIRQUANTUM INDEX REPORT Back 10. Quantum Processor Benchmarking Two dozen manufacturers are commercially offering more than 40 quantum processing units (QPUs) today. The United States leads the field, both in terms of the number and diversity of QPUs, followed by China. However, China’s commercially available QPUs tend to be smaller and have lower performance compared

The Hidden Geometry That Could Explain the Universe

How can the tiniest particles and the vast structure of the universe be explained using the same kind of mathematics? This puzzle is the focus of recent research by mathematicians Claudia Fevola (Inria Saclay) and Anna-Laura Sattelberger (Max Planck Institute for Mathematics in the Sciences), published in the Notices of the American Mathematical Society.

Interesting new paper out demonstrating #quantum teleportation between telecom-wavelength photonic qubits and solid-state quantum memory (erbium-ion ensembles). This is a step towards improving the range and utility of quantum networks (realization of scalable quantum networks based on solid-state devices), as well as laying more foundation for distributed quantum computing (see the Oxford breakthrough discussed on Entangled Things podcast ep. 113)

Quantum #physics is often described as the most successful scientific framework in history.

In its 100 years of existence, it has explained everything from the periodic table of the elements to how #stars shine.

But there is one fundamental phenomenon it can’t explain: #gravity.

Generations of researchers have tried to create a #quantum theory of gravity, and their work has produced sophisticated mathematical constructs, such as string theory.

But experimental physicists haven’t found concrete evidence for any of these, and they’re not even sure what such evidence could look like.

Now there is a sense that insights could be around the corner.

In the past decade, many researchers have become more optimistic that there are ways to test the true nature of gravity in the laboratory.

Ah, the timeless art of #systemd "hardening"—because who doesn't love adding ✨extra GUARDRAILS✨ to a #technology that's already as #intuitive as #quantum physics? 🤯 Just follow this thrilling #cycle of adding directives, reloading, and restarting until you attain nirvana or fall asleep at your keyboard. 💤
