"overcomes physical barrier historically restricting technologies' sensitivity for use in advanced science... single-photon entanglement improved precision but failed to provide high resolution, overcome using multi-mode N00N State entangling multiple photons along specific paths creating much denser interference fringes, detecting smallest physical changes with high sensitivity, simultaneously enhancing resolution... 88% higher precision (2.74 dB improvement), approaching ultimate Heisenberg limit... future: chip-based"
