I really like this interpretation:
"before decoherence takes place, all the #quantum possibilities are in some sense present. But #decoherence and quantum #Darwinism select only one of them as an element of our observable reality, without any need to assign all the others a classical reality in some other world. The other states exist in an abstract space of possibilities, but they stay there, never getting the chance to grow via entanglement into observable realities."

🌐 The security community has moved 🔐protocols over the last decade from RSA to elliptic curves, allowing for smaller key sizes

⚛️ While #quantum algorithms research focused around optimizing Shor’s (breaking RSA), a new result shows that breaking the elliptic curve discrete logarithm problem requires significantly less qubits than previously thought.

⚠️ Breaking P-256, which has equivalent classical security to RSA-3072, only requires 1193 logical qubits against 2043.

⚛️ News from quantum physics: So-called Anyons are exotic particles that are neither bosons nor fermions. A team from Innsbruck, Brussels, and Paris has found a simple yet powerful way to detect anyons—by swapping two spins.

#introduction
Hello! I am Originalbarbas and I have recently joined this server. I am a physicist, currently researching #quantum technologies in #Vigo. I build things with lasers on them, basically. Sometimes I also build the lasers too. I have lived in many places, recently in #Scotland and #Catalunya.

I like #videgames (currently playing through Expedition 33), #tabletopgames, #ttrpgs, #manga, #anime, #books (I read everything that I get my hands into, but I specially like #scifi, #fantasy and #murdermysteries), #comics (european mostly, but also american and basically every genre I can find), #bouldering and recently #aikido and #iaido.

Pleased to be in your nice company!

P.S. I might write another in Spanish, maybe tomorrow.

There's a new tech bubble rising up in the horizon:

"An analysis of 58,070 corporate communication documents — such as company reports, transcripts of interviews with experts, and research documents — from 2022 to 2024 revealed increasing references to quantum computing, suggesting an expanding awareness of quantum and its inclusion in mainstream business discussions, not just technical discourse, the researchers found. News-related corporate communications content saw particularly pronounced increases.

References to quantum computing in corporate communications more generally escalated in 2024, with each quarter showing substantial increases in mentions across all forms of company documents. “While research documents naturally maintain high levels of quantum computing references, the significant increase in mentions across other document categories ... might suggest a growing understanding of the technology’s presence in corporate communications,” the researchers write.

References to quantum technologies are also becoming more common in corporate earnings calls, growing more than sixfold from 2016 to 2024. Much of the heightened attention can be associated with major players actively integrating quantum computing into their strategic roadmaps — for example, IBM expanding its quantum facilities and launching new initiatives and AI powerhouse Nvidia announcing partnerships with quantum startups.

As quantum technologies are more frequently discussed in C-suite and financial circles, markets are taking notice. A Technavio report estimated that the global quantum computing market will grow by $17.34 billion from 2024 to 2028, achieving a compound annual growth rate of 26%. Startup investment is also on the rise, evidenced by a $300 million equity infusion for quantum computing company Quantinuum in 2024."

Physicists Take the Imaginary Numbers Out of Quantum Mechanics

@cstross @skjeggtroll Moore’s Law is dead for now. I did a study a few years ago to look at what is happening and will happen in microprocessors. Short story is that traditional processor architecture is hitting end of life. Feature sizes are so small now that quantum effects are a significant factor. High speed and small size also means we are up against a thermal barrier as well. Clever approaches with System-On-a-Chip ( #SOA), 3D stacking, maybe Processor-In-Memory ( #PIM) and distributed multiprocessing will squeeze out more progress for maybe a decade. After that comes the next computing revolution — a shift to non-Von Neumann #computing. #Quantum has the spotlight because that’s the really big win, but there are other approaches that are likely to be commercially viable before quantum is mature. I’m optimistic about the tech, less so about the rate of adoption and change that will be required, especially if the most talented early- career computer scientists and engineers keep chasing the associative/statistical methods that include LLMs.

I like watching popular science type videos. Everybody who tries to explain quantum mechanics always uses the word "collapse" and they always pull it out of nowhere and make no effort to describe what the hell they're talking about. Why is this? Are they being paid off by the dictionary people to use specifically that word or something? Do I have to actually learn physics if I want to know what's going on here?
