Beam Tracking Beyond the Heisenberg Uncertainty Limit
Determining a beam’s full trajectory requires tracking both its position and momentum. However, the uncertainty product of the two parameters is bounded by the Heisenberg uncertainty limit (HUL). Here, we demonstrate a quantum beam tracking technique by leveraging position and momentum entangled photons to achieve an accuracy beyond the HUL.
