This a tangent to the topic of the article, but it is an interesting tangent: There are many ways in which having coherent quantum states permits better sensors (sensing anything that is related to a Electric/Gravitational/Magnetic field, voltage, current, intensity, frequency, so basically all kinds of areas).

- coherent superposition of multiple sensors improve the signal to noise ratio

- improving beyond the diffraction limit of telescopes, by quantum-entangling multiple sensors

- using constructs similar to quantum error correcting codes to make measurements more resilient to noise

And these above are just the generic suggestions that are discussed in grad classes. When you dig into it there are so many other amazing quantum tricks to do.
