Cryptographic algorithms are what keep us safe online, protecting our privacy and securing the transfer of information.

But many experts fear that quantum computers could one day break these algorithms, leaving us open to attack from hackers and fraudsters. And those quantum computers may be ready sooner than many people think.

That’s why there is serious work underway to design new types of algorithms that are resistant to even the most powerful quantum computer we can imagine. Read our emerging journalist fellow Tammy Xu’s full story on how quantum-resistant algorithms are being developed—and what comes next.

This is part of Tech Review Explains: where our writers untangle the complex, messy world of technology to help you better understand what comes next. Check out our other smart explainers here.
