What's up in
Quantum computers can’t selectively forget information. A new algorithm for multiplication shows a way around that problem.
By chopping up large numbers into smaller ones, researchers have rewritten a fundamental mathematical speed limit.
Neural networks are famously incomprehensible, so Been Kim is developing a “translator for humans.”
The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.
Digital security depends on the difficulty of factoring large numbers. A new proof shows why one method for breaking digital encryption won’t work.
