Two completely different quantum systems were successfully joined at Vienna University of Technology (TU Vienna). This should pave the way to feasible quantum-computer microchips.
For years, quantum computers have been the holy grail of quantum technology. When a normal computer has to solve a number of problems, it can only execute them one after the other. In contrast, a quantum computer could occupy several different states at the same time -- and that way it could try out different possible solutions of a problem at once, finding the correct answer much faster than a normal computer ever could.
