First 3D quantum accelerometer may let ships navigate with out GPS

A tool that measures acceleration very exactly utilizing quantum results might be used for navigation when GPS is unavailable

By Karmela Padavic-Callaghan

A quantum gadget that may decide its place in three dimensions is extra correct than non-quantum variations. Automobiles may use it to navigate even if GPS stopped working.

One technique to preserve monitor of one thing’s place is with an accelerometer, which is a small gadget that’s present in all the things from telephones to drones. Accelerometers work by detecting adjustments in motion and subsequently place.

It has been recognized for many years that quantum results might be used make extra correct accelerometers, however most …
