More than 20% of the workload on the world's 500 fastest supercomputers is spent simulating how atoms and molecules move—with applications ranging from material design to identifying drug interactions ...

Encryption systems rely on “random” numbers, but conventional computers can’t generate them perfectly. New research shows that quantum physics can.

Abstract: Karatsuba algorithm (KA) is popularly used for high-precision multiplication by divide-and-conquer approach. Recently, subquadratic digit-serial multiplier based on (a,2)-way KA ...

RSA encryption protects everything from your Amazon purchases to your bank transfers. But quantum computing presents a fundamental challenge to this security. I dove into the math to understand ...

Is 170,141,183,460,469,231,731,687,303,715,884,105,727 prime? Before you ask the Internet for an answer, can you consider how you might answer that question without a ...

In 1971, German mathematicians Schönhage and Strassen predicted a faster algorithm for multiplying large numbers, but it remained unproven for decades. Mathematicians from Australia and France have ...

A shard of smooth bone etched with irregular marks dating back 20,000 years puzzled archaeologists until they noticed something unique – the etchings, lines like tally marks, may have represented ...

The original version of this story appeared in Quanta Magazine. For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a ...

Imagine a number made up of a vast string of ones: 1111111…111. Specifically, 136,279,841 ones in a row. If we stacked up that many sheets of paper, the resulting tower would stretch into the ...

Thousands of computers across the world are currently scouring the number line in a scavenger hunt for rare mathematical gems. Enthusiasts looking for larger and larger prime numbers, which are ...
