Continuous Atom Reloading in Neutral-Atom Qubits: A Subsystem Result, Not Yet a Fault-Tolerant One
Evidence-first notes on bioscience and deep tech, at the edge of the lab and the market. Information only — not investment advice. This post covers a peer-reviewed physics paper describing one subsystem of a neutral-atom quantum computer: how quickly a lost or used-up atomic qubit can be replaced from a reservoir without disturbing the qubits…

Three levers on fault-tolerance overhead — and why they sit on three different evidence tiers
Evidence-first notes on bioscience and deep tech, at the edge of the lab and the market. Information only — not investment advice. The 30-second version What. Fault-tolerant quantum computing has one dominant cost: the number of physical qubits and operations needed per useful logical qubit. Four results from 2026 push on that cost from three…

The honest TRL of post-CMOS: the gap between headline qubit counts and the “when is it useful?” question
Evidence-first notes on bioscience and deep tech, at the edge of the lab and the market. Information only — not investment advice. The 30-second version What. For post-CMOS alternatives (quantum, neuromorphic, photonic and others), the real question is not “does it work?” but “when does it become useful?” The estimated resources to break RSA-2048 have…

A compiler for the wiring between error-correcting codes — a theory-layer step, not a hardware milestone
Evidence-first notes on bioscience and deep tech, at the edge of the lab and the market. Information only — not investment advice. The 30-second version What. A new preprint (Benhemou & Berthusen, arXiv, 2 July 2026) gives an automated way to design the logical gate — a logical CNOT or CZ — that connects two…
