What are quantum-resistant algorithms—and why do we need them?

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.

The big story

Inside the rise of police department real-time crime centers

April 2021

At a conference in New Orleans in 2007, Jon Greiner, then the chief of police in Ogden, Utah, heard a presentation by the New York City Police Department about a sophisticated new data hub called a “real time crime center.”

In the early 1990s, the NYPD had pioneered a system called CompStat that aimed to discern patterns in crime data, since widely adopted by large police departments around the country. With the real time crime center, the idea was to go a step further: What if dispatchers could use the department’s vast trove of data to inform the police response to incidents as they occurred?

Around the country, the expansion of police technology has been driven more by conversations between police agencies and their vendors than between police and the public they serve. And as federal and state laws take their time to catch up, who gets to decide how close a tool can really get to your constitutional rights? Read the full story.
