Observation of Young's Double-Slit Interference with the Three-photon N00N state

Yong‐Su Kim, Osung Kwon, Sang Min Lee +4 more

We report the first experimental observation of a three-photon N00N state exhibiting Young’s double-slit type spatial quantum interference. Compared to a single-photon state, the three-photon entangled state generates interference fringes that are three times denser.

Reviving Young's slits in an atom

Helen H. Fielding

There has always been a desire to understand quantum mechanics in terms of classical physics. Quantum analogues of Young's double-slit experiment from classical optics have been fundamental to our understanding of the wave nature of particles and double-slit interference patterns have been observed with beams of electrons and atoms. Now, Michael Noel and Carlos Stroud of the University of Rochester in the US have observed double- slit-like interference phenomena in electron wave packets within a single atom (M W Noel and C S Stroud 1995 Phys. Rev. Lett. 75 1252).

Two-photon interference behind Young’s double slit

Martin P. van Exter, J. J. Renema, Wouter H. J. Peeters

We have observed two-photon interference behind Youngpsilas double slit with unprecedented signal/noise ratiopsilas. We demonstrate the complementarity between quantum entanglement in the two-photon field and optical coherence in the projected one-photon field for three different types of illumination: far-field, near-field, and intermediate illumination.

Double Slit to Non-parallel Double Slit to Curved Double Slit

Hui Peng

Young’s double slit experiment was called as "a phenomenon […] has in it the heart of quantum mechanics. In reality, it contains the only mystery. We cannot make the mystery go away by ‘explaining’ how it works". To study the mystery, we perform the non-crossing-slit-experiments and crossing-slit experiments and show phenomena: (1) in the same double slit or cross double slit experiments, the non-interference patterns gradually evolve to the interference patterns; (2) in the same single slit or cross single slit experiments, the non-diffraction patterns gradually evolve to the diffraction patterns; (3) in the same two-non-parallel-slits experiment, the non-wave patterns gradually evolve to the hybrid pattern (i.e., interference-pattern-embedded-in-diffraction-pattern); (4) in the same curved-double slit experiments, the non-interference patterns evolve to Seashell-shape interference patterns. The above phenomena show new mysteries that are more mysterious than that of the double slit experiments: it is challenge to consistently explain how they work. Those novel phenomena indicate that the standard theories of the double slit are incomplete. Novel experiments bring the search for the new theory of physical/quantum optics.
