DESCRIPTION
Physicists have theorized that a new type of material, called a three-dimensional (3-D) topological insulator (TI), could be a candidate to create qubits for quantum computing due to its special properties. A study found that when the TI's insulating layers are as thin as 16 quintuple atomic layers across, the top and bottom metallic surfaces begin to destroy their metallic properties.
