"Time-Squeezed Light Waves Reveal Unexpected Physics in Double-Slit Experiment"

Scientists have demonstrated a temporal version of the double-slit experiment, showing that light can diffract in time as well as space. Using a semiconductor common in phone screen manufacturing, the team created a double-slit in time by delivering two quick consecutive pulses at the right time for the right wavelengths of light. The interference patterns created in the time version of the experiment affect the frequency of light, changing its colors. The team believes this technology could have applications in data encoding and time crystals.
