We introduce a novel interferometry technique where a probe particle interacts with a target particle in a superposition of locations. This method allows for the swapping of interference patterns, offering new insights into quantum mechanics.

Area of Science:

  • Quantum mechanics
  • Quantum optics
  • Interferometry

Background:

  • Quantum interference is a fundamental phenomenon.
  • Previous interferometry methods typically involve fixed or multiple targets.
  • Understanding particle interactions in superposition states is crucial.

Purpose of the Study:

  • To introduce a new interferometry technique using a single free target particle in a superposition of locations.
  • To demonstrate the phenomenon of interference swapping between probe and target states.
  • To analyze the conditions and parameters required for observing this novel interference.

Main Methods:

  • Developing a theoretical framework for a new interferometry setup.
  • Utilizing a probe particle scattering off a single free target particle in a superposition of positions.
