By employing a technique called scanning tunnelling microscopy lithography, the scientists are able to directly measure each atom’s wavefunction, thereby determining its exact location in the chip. “We are the only group in the world who can actually see where our qubits are,”
The notion of a wave function refers to a way of describing quantum objects, including individual particles and more complex systems. A wave function assigns a value called probability amplitude to all points in space. The terms “wave” and “amplitude” imply that the objects described by wave functions behave much like waves.
