University of Cologne tests a path to stable qubits
University of Cologne physicists observed quantum states supporting a path toward more robust quantum bits, key for error reduction.
A Josephson junction combining a topological insulator and a superconductor, featuring a closed loop for magnetic phase control, is at the heart of new findings from the University of Cologne. Their work, published in Science Advances under the title “Tunneling spectroscopy of topological insulator Josephson junctions,” directly supports theoretical predictions about how superconductivity interacts with topological insulator…
