RSA-2048 Cracked in 177 Days With ~13K Processing Qubits? New Preprint Trades Qubits for Quantum Memory.
A new preprint by Elie Gouzien and Nicolas Sangouard proposes an architectural trade: replace the “millions of qubits in one giant chip” model with a small quantum processor plus a very large multimode quantum memory. Under optimistic - but clearly stated - fault-tolerance assumptions, the…

Lattice Surgery
Quantum computing promises to solve complex problems far beyond the reach of classical machines, but today's quantum hardware is plagued by short-lived qubits and error rates that make long computations infeasible. Quantum error correction (QEC) is essential to stabilize qubits…

Part 11: Reading the Field Like a Professional
The series closes by turning ten parts of physics into working equipment: how resource estimates move, which milestones matter, the standing answers to the questions you will be asked, and the deadline that was never Q-Day.

Part 10: The Machine Itself
Part 10 builds the machine every earlier part assumed. Decoherence is the environment measuring your qubits uninvited, error correction checks integrity without reading the data, and the number in the headline is almost never the number that matters.

Part 9: Grover and the Honest Speedup
Part 9 covers the algorithm that attacks everything Shor cannot. Grover's quadratic speedup is real, provably optimal, and far weaker in practice than the halving figure suggests, for a reason NIST wrote into its own standards.
