Q-Day Predictions: Anticipating the Arrival of CRQC
While CRQCs capable of breaking current public key encryption algorithms have not yet materialized, technological advancements are pushing us towards what is ominously dubbed 'Q-Day'—the day a CRQC becomes operational. Many experts believe that Q-Day, or Y2Q as it's sometimes…

Homomorphic Encryption for ML: What the Overhead Buys
Homomorphic encryption lets an untrusted server compute on data it cannot read. The overhead is severe enough that the set of machine learning workloads where that trade is correct is small, specific and worth naming precisely.

Quantum Readiness for Mission-Critical Communications (MCC)
Mission-critical communications (MCC) networks are the specialized communication systems used by “blue light” emergency and disaster response services (police, fire, EMS), military units, utilities, and other critical operators to relay vital information when lives or infrastructure are at stake. These…

What 250 Poisoned Documents Actually Proved
Two hundred and fifty documents planted the same backdoor in models from 600M to 13B parameters. What it planted was gibberish on a trigger word. The poisoning that should worry defenders is somewhere else entirely.

Semantic Adversarial Attacks: Leaving the Perturbation Budget Behind
A semantic attack changes the lighting, the hair colour or the phrasing. The result is enormous in pixel distance, obviously the same thing to a person, and outside the set of inputs any robustness guarantee was written about.

Intel’s Tunnel Falls: 24,000 Quantum Chips Per Wafer and the Manufacturing Argument Made Real
22 Jun 2023 - Every conversation about silicon spin qubits eventually arrives at the same claim: because these qubits are essentially single-electron transistors, they can be manufactured using the same processes that produce billions of classical transistors every year. The…
