from niobium and operates in a magnetic field as powerful as 7.2 Tesla.
Last August, physicists in Switzerland successfully teleported information 6 millimeters between two corners of a superconducting chip made
from niobium, sapphire and aluminum; the superconducting chip is the basic building block for a quantum computer.
Quantum teleportation of data across a superconducting chip (like this one made
from niobium, sapphire and aluminum) is essential for quantum computing.

When the tip of the microscope oscillates over certain surfaces, in this case over NbSe2 (
niobium selenide), peaks of «dissipation» (i.e., loss of energy) can be seen when the tip is at specific distances
from the surface, as if it were held back, at certain locations, by some frictional force.
