Mathematicians Discover the Perfect Way to Multiply
By chopping up large numbers into smaller ones, researchers have rewritten a fundamental mathematical speed limit.
Cryptography That Is Provably Secure
Researchers have just released hacker-proof cryptographic code — programs with the same level of invincibility as a mathematical proof.
How Artificial Intelligence Is Changing Science
The latest AI algorithms are probing the evolution of galaxies, calculating quantum wave functions, discovering new chemical compounds and more. Is there anything that scientists do that can’t be automated?
A New Approach to Understanding How Machines Think
Neural networks are famously incomprehensible, so Been Kim is developing a “translator for humans.”
How Space and Time Could Be a Quantum Error-Correcting Code
The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
The Year in Math and Computer Science
Several mathematicians under the age of 30 left their marks all over the field, and amateur problem-solvers of all ages made significant contributions to long-dormant puzzles.
Milestone Experiment Proves Quantum Communication Really Is Faster
In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.
Mathematicians Seal Back Door to Breaking RSA Encryption
Digital security depends on the difficulty of factoring large numbers. A new proof shows why one method for breaking digital encryption won’t work.
Graduate Student Solves Quantum Verification Problem
Urmila Mahadev spent eight years in graduate school solving one of the most basic questions in quantum computation: How do you know whether a quantum computer has done anything quantum at all?
