Keeping Things Private in the Age of Quantum Computing?

The OG Podacst: Keeping things private in the age of Quantum computing, with Dr Craig Costello
"Dr. Craig Costello is a Senior Researcher in the Security and Cryptography group at Microsoft Research in Redmond, USA.

Where his job is to keep what you want secret a secret - basically using some very complex mathematics.
He is among a formidable group of cryptographers whose life’s work is to protect the internet against adversarial code breakers (aka cryptanalysts), both those that exist today in our classical computing world, and those that will exist in a quantum computing future.
Needless to say - he knows what he’s talking about when it comes to the security of you and your data in an online world."

There's always something or someone trying to bug ya these days it seems, but what's the answer to it all?-)

UPDATE:

I thought I would tag this 'Cosmic Keys' podcast below onto to this post, as it's kind of relevant to the subjects touched on above, especially the future of the WWW.

And if you find it isn't relevant, at least you might find the discussion interesting at least.
