SUMMARY

This discussion focuses on the exploration of temporal complementarity in single- and two-photon interference, specifically regarding coherence and entanglement in the temporal domain. The original poster (OP) suggests that utilizing a similar experimental setup as in spatial interference, with a time delay between photons, could yield insights into this phenomenon. The OP also speculates that relevant experiments may have already been conducted but seeks confirmation or references to such studies.

PREREQUISITES
  • Understanding of quantum optics principles
  • Familiarity with single-photon and two-photon interference techniques
  • Knowledge of coherence and entanglement in quantum mechanics
  • Experience with experimental setups involving time delays in photon detection
NEXT STEPS
  • Research existing experiments on temporal complementarity in quantum optics
  • Examine papers on coherence and entanglement in the temporal domain
  • Study the methodologies used in spatial interference experiments
  • Learn about time delay techniques in photon experiments
USEFUL FOR

Quantum physicists, researchers in quantum optics, and students studying interference phenomena will benefit from this discussion.

I am looking for:

Any experiment/paper that shows -

complementarity between single- and two-photon interference (coherence and entanglement) in the Temporal domain.
 
Physics news on Phys.org
On second thoughts this should be easy just use the same setup as in the spatial and create time delay between photons. I wonder why the authors did not do that. The OP concludes... perhaps such experiments have already been done.
