Phys.org  April 24, 2019 A theory developed only two years ago proposed a way to make qubits more resilient through combining a semiconductor, indium arsenide, with a superconductor, aluminum, into a planar device. An international team of researchers (Denmark, USA – University of Chicago, Purdue University, Israel) has provided experimental support to the theory in a device that could also aid the scaling of qubits. These experiments provide evidence that aluminum and indium arsenide, when brought together to form a device called a Josephson junction, can support Majorana zero modes, which scientists have predicted possess topological protection against decoherence. The […]
