Precision sensing experiment manipulates Heisenberg’s uncertainty principle

Though the principle is not violated, a new way of fudging its restrictions could lead to improvements in ultra-precise sensing, say physicists

An illustration showing how vibrations in one side of the splitter become coupled to the other side. The two waveguides are shown as long, narrow purple blocks that overlap for part of their length. In the area of overlap, a big blue-and-yellow wave envelope that enters the picture via one waveguide is split into two smaller-magnitude wave envelopes travelling through both waveguides.
