A Viral Paper Claims Lattice-Based PQC Has “Fundamental Limitations” — The Arguments Are Old and the Conclusion Is Wrong
A Seoul National University paper arguing lattice-based cryptography has "fundamental limitations" is generating alarming headlines. The theoretical points are valid but well-known. What the paper actually demonstrates is why PQC migration should accelerate, not stall.

IonQ’s Q-Day Claim: What the Earnings Call Actually Said vs. the Panic It’s Feeding
IonQ's CEO told investors the company will reach the logical qubit count to "challenge RSA-2048" by 2028–2029. That's not the same as breaking encryption, and the Q-FUD machine is already running at full speed.

Architecture Matters as Much as the Algorithm: Q-CTRL’s Heterogeneous Quantum Computer Design Cuts RSA-2048 to 190k-381k Qubits
9 Apr 2026 - Researchers at Q-CTRL, a quantum infrastructure software company headquartered in Los Angeles and Sydney, have published a paper introducing Q-NEXUS, a heterogeneous quantum computing architecture that claims to reduce the physical qubit requirements for factoring 2048-bit RSA integers to as few as 190,000 physical qubits — a roughly 4.7× reduction from the current monolithic baseline. The…

10,000 Qubits to Run Shor’s Algorithm
31 Mar 2026 - On the same day that Google Quantum AI published its landmark ECDLP-256 resource estimates showing fewer than 500,000 superconducting qubits could break cryptocurrency cryptography in minutes, a team from Oratomic, Caltech, and UC Berkeley quietly dropped a paper making an even more startling claim about qubit count: Shor's algorithm can be executed at cryptographically relevant scales…
