The Architect of Modern Algorithms
Barbara Liskov pioneered the modern approach to writing code. She warns that the challenges facing computer science today can’t be overcome with good design alone.
Playing Hide-and-Seek, Machines Invent New Tools
After millions of games, machine learning algorithms found creative solutions and unexpected new strategies that could transfer to the real world.
Computers Evolve a New Path Toward Human Intelligence
By ignoring their goals, evolutionary algorithms have solved longstanding challenges in artificial intelligence.
Google and IBM Clash Over Milestone Quantum Computing Experiment
Today Google announced that it achieved “quantum supremacy.” Its chief quantum computing rival, IBM, said it hasn’t. The disagreement hinges on what the term really means.
Mathematicians Begin to Tame Wild ‘Sunflower’ Problem
A major advance toward solving the 60-year-old sunflower conjecture is shedding light on how order begins to appear as random systems grow in size.
Machines Beat Humans on a Reading Test. But Do They Understand?
A tool known as BERT can now beat humans on advanced reading-comprehension tests. But it's also revealed how far AI has to go.
Why I Called It ‘Quantum Supremacy’
Researchers finally seem to have a quantum computer that can outperform a classical computer. But what does that really mean?
Solution: ‘Perfect Randomness’
Is nature inherently random or is perfect randomness just an illusion based on our ignorance?
To Invent a Quantum Internet
Fifty years after the current internet was born, the physicist and computer scientist Stephanie Wehner is planning and designing the next internet — a quantum one.
