Qeli is an open-source VPN you run on your own server. No third-party service, no account with someone else, no telemetry - the server is yours, the keys are yours, and the software itself sends nothing to me or anyone else. The core and server are written in Rust. This is a full tour: what it is, how it is built, how to stand one up, and where it honestly stands today. The model: your server, yo…

I maintain Qeli , a self-hosted VPN whose core and server are written in Rust. For the 0.7.x line I added a hybrid post-quantum key exchange to the inner handshake, and wired the same primitive into the non-Rust clients. Here is how it is built and what bit me. Why hybrid, not pure PQ The threat is "harvest now, decrypt later": traffic captured today, decrypted once a large quantum computer exist…

Something big just happened in India. And if you haven’t heard about it yet, you’re going to want to read this. Andhra Pradesh has officially launched India’s first indigenous quantum computing testbeds in Amaravati. This is not just a win for the state. It’s a massive leap forward for the entire country’s technology future. Let’s […] The post Andhra Pradesh Makes History: India’s First Indigenou…

Insurance involves hard problems with complex, correlated risks. Allstate and IBM are showing how quantum could help solve them.

A public-private partnership in the Mountain West has announced new results that mark steady progress toward the Department of Energy's goal of fault-tolerant quantum computing, systems large and reliable enough to solve complex problems.

Elsewhere, beyond-classical quantum hardware, plus classical computing fires back.

Nature, Published online: 17 June 2026; doi:10.1038/d41586-026-01702-6 A quantum computer based on trapped ions can connect any two quantum bits, reaching performance levels that conventional computers cannot match.

Nature, Published online: 17 June 2026; doi:10.1038/s41586-026-10635-z By embedding core computer vision principles into a large-scale optical metasurface, an efficient vision processing system using far fewer parameters is demonstrated to outperform many digital models and enables deployment on edge devices.

Nature, Published online: 17 June 2026; doi:10.1038/s41586-026-10676-4 A new quantum computer, Quantinuum Helios, which is a 98-qubit trapped-ion quantum processor built on the QCCD architecture, demonstrates performance well beyond classical capabilities and provides a path for scaling up quantum computing.

A research team led by Senior Researcher Hyeong-U Kim of the Semiconductor Manufacturing Research Center at the Korea Institute of Machinery and Materials (President Seok-Hyeon Ryu, hereinafter referred to as KIMM) developed synthesis and etching processes for 6-inch next-generation 2D semiconductors (MoS₂ and WS₂) using low-temperature plasma-based PECVD and RIE equipment and implemented them in…

Leveraging the computation capability of the sensor itself, we present a spectral sensor that directly decodes application-relevant spectral information from light. This approach bypasses a large amount of raw sensory data, enabling more efficient spectroscopic recognition.

Quantum computing has long been viewed as one of the most promising technologies of the future, and 2026 is bringing new signs of progress. Major technology companies and research institutions continue to invest billions into developing more stable and scalable quantum systems capable of solving problems beyond the reach of traditional computers. Recent advances have […]
