Design links quantum bits Realizing the potential of phenomenally fast quantum computers means having to link thousands of quantum bits, which are the transistors of such computers. So far researchers have been able to connect only a few. A scheme for linking many tiny superconducting loops may pull it all together. |

Electron teams make bigger qubits Making quantum computers from electronic chips rather than cumbersome laboratory equipment requires control over individual electrons. A scheme that has a string of electrons acting as one could ease the task by expanding the target to a whopping 250 millionths of a millimeter. |
