Development of quantum computers may be expedited by collaboration between physicists and chemists. Quantum computer power will dwarf that of today’s machines, with huge implications for cryptography, computational chemistry and other fields. While qubits can take many different forms, the MagLab team worked with carefully designed tungsten oxide molecules that contained a single magnetic holmium ion. The magnetic electrons associated with each holmium ion circulate either clockwise or counterclockwise around the axis of the molecule. These spin states are analogous to the “0s” and “1s” of computer bits...
