The concern: hackers and intelligence agencies could use advanced quantum attacks to crack current encryption techniques and learn, well, anything they want. Now Google is starting the slow, hard work of preparing for that future, beginning with a web browser designed to keep your secrets even when they're attacked by a quantum computer more powerful than any the world has seen.

The search giant today revealed that it's been rolling out a new form of encryption in its Chrome browser that's designed to resist not just existing crypto-cracking methods, but also attacks that might take advantage of a future quantum computer that accelerates codebreaking techniques untold gajillions of times over.
