For decades, computers have relied on digital logic and binary code. That approach is now running into physical and economic limits. Engineers are revisiting analog computing, a method once considered ...

Quantum computers will break encryption one day. But converting data into light particles and beaming them around using thousands of satellites might be one way around this problem. When you purchase ...

Peter Shor published one of the earliest algorithms for quantum computers in 1994. Running Shor's algorithm on a hypothetical quantum computer, one could rapidly factor enormous numbers—a seemingly ...

Many experts believe that once quantum computers are big enough and reliable enough to solve useful problems, the most common deployment architecture will be to have them serve as accelerators for ...

The encryption protecting billions of dollars, which experts once called unbreakable, no longer works. Hackers don’t need passwords. They don’t brute-force keys. They simply walk through digital ...

For some reason, we often think of computers as infallible -- subjective, logical, rational, and nearly always right. There is something about a computer's lack of emotion and intelligence that makes ...

If you’ve heard of the game Minecraft, you may also have heard about all the folks who’ve built working virtual arithmetic logic units (ALUs) out of the LEGO-like game world itself. Sure, they’re more ...
