According to cryptographer Dr. Sushmita Ruj from the University of New South Wales, it's all pretty cutthroat.

cutthroat.Once you see a design and you put on your attacker's hat and really try to break it, even if it is your friend who has written this algorithm, you still put on that attacker's hat and you try to break it.

And because we don't know when or even if Q-Day will arrive, it's easy to put off.

It's very hard to say when we might get a quantum computer, but what I see from the advances that are happening in the quantum space as well, it's something that we need to do very timely, very soon.

I mean, we have to start now.
