Voor de Quantum-nerds. :) Eindelijk.... Mijn Full-Post-Quantum Cryptography website draait met mijn eigen ML-DSA 87 Root/Sub CA en MLDSA 65 webserver certificaat. https://pqc.rawdutch.nl Edit: En natuurlijk mijn Quantum domein: https://pqc.
Somewhere right now, someone is storing encrypted traffic they can't read. They aren't cracking it. They're waiting for a machine that doesn't fully exist yet. It's called "harvest now, decrypt later," and it's one reason quantum computing
New paper: Shor’s on about ~23K cat qubits can factor RSA-2048 in 3.14 days (however: assumes near-zero bit flips, which is not realistic yet) #quantum https://eprint.iacr.org/2026/2665
What “quantum” means
Wiktionary · Wikipediaquantum[ˈkwɑɾ̃əm]
- nounThe total amount of something; quantity.
- adjectiveOf a change, sudden or discrete, without intermediate stages.
In physics, a quantum is the minimum amount of any physical entity involved in an interaction. The fundamental notion that a property can be "quantized" is referred to as "the hypothesis of quantization". This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum. For example, a photon is a single quantum of light of a specific frequency. Similarly, the energy of an electron bound within an atom is quantized and can exis

every network with a public tag surfaceFollow #quantum straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/quantum
