It’s a matter of time until the day arrives when quantum computers will crack traditional encryption. This moment, often referred to as “Y2Q,” may be as little as three to five years away, given the billions of dollars of investment flowing into the field.
While we can’t be sure of the exact date of Y2Q, we can be sure of what quantum will mean in comparison with today’s computers and more specifically what it means for today’s security standards.
