Researchers at The Johns Hopkins University have found that a certain superconducting material contains special properties that could be the building blocks for quantum computers. The findings will be published October 11 in Science.
The team has discovered that a ring of β-Bi2Pd already naturally exists between two states in the absence of an external magnetic field. Current can inherently circulate both clockwise and counterclockwise, simultaneously, through a ring of β-Bi2Pd. This is a tangible implementation of flux qubit where two states with clockwise- and counterclockwise-flowing electric currents may exist simultaneously. (Johns Hopkins University)
