Q-Day Is a Confidence Crisis, Not an Outage
The morning a quantum computer factors an RSA-2048 key, nothing goes dark. What ends is the presumption of safety, and the questions start within…
Trust Now, Forge Later: The Signature Half of the Migration
Harvest Now, Decrypt Later sets its clock by data retention. The signature side of the quantum problem sets its clock by deployment lifetime, and…
Who Really Wins If Photonics Wins
The photonic bet is a manufacturing bet. Which means the winners, if it pays off, are decided layer by layer, and most of them…
Who Really Wins If Trapped Ions Win
Trapped-ion quantum computing has no single chokepoint like the dilution refrigerator. It has a contested one, and most of it sits in Europe while…
The Deadlines That Already Bind Your Cryptography
