Virtually every device you use—from the one you're using to read this to the pocket calculator growing dust in the back of your desk—relies on the same basic technology: circuits containing many tiny transistors that communicate with each other using electrons. We've come a very long way since the room-sized computers of the 1950s, but as computing gets smaller, faster, and more complicated, we get closer to hitting a wall. There's a physical limit to how powerful traditional computers can get. That's why scientists are turning to completely new forms of technology for future computers.
For the first two parts of our three-part series on the future of computing, we explored what computers might be like if they thought like humans or used photons to move information. Now find out what happens when those two technologies become one.
