Quantum computers could crack codes and run more complex simulations than current machines, but actually building one is hard to do. The bits that store this complex data don’t last long, because they are made of single atoms that get knocked around by stray electrons and photons in the environment.
Enter a team of physicists at Germany’s Karlsruhe Institute of Technology. They found a way to get the bits to last long enough to do computations with, using the magnetic properties of a rare earth element called holmium and the symmetry of platinum. The experiment, detailed in tomorrow’s (Nov. 14) issue of the journal Nature, is an important step in creating quantum computers and making quantum memory useful.
What makes quantum computers powerful is the nature of the bit. Ordinary computers have bits that are 1 or 0, stored in the current in a circuit or the alignment of magnetic fields on a disk. Due to the weirdness of quantum physics, quantum bits, called qubits, can be both 0 and 1 at the same time. That means a quantum computer can do certain kinds of calculations much, much faster.

To discover the deepest mysteries of the universe, no ordinary computer will do. Solving some of the most challenging computer science problems — notably toward the advancement of machine learning — will require quantum computing. To that end, Google announced that it is launching the Quantum Artificial Intelligence Lab with NASA’s Ames Research Center, which will host the lab.
This facility will house a new quantum computer from D-Wave Systems and the Universities Space Research Association. Researchers from around the world will share time on it, with the common goal of studying how quantum computing might advance machine learning.
