The discussion centers on the potential for this year's Nobel Prize to be awarded in the field of quantum cryptography, specifically mentioning candidates Charles H Bennett, Gilles Brassard, and Artur Ekert. It highlights the Nobel committee's tendency to recognize inventions that have reached maturity, are deployed, and have significantly impacted society. Examples of such recognized innovations include the transistor, bubble chamber, optical tweezers, and white LED. The conversation suggests that while quantum cryptography shows promise, the committee may still be waiting for broader societal impact before making an award in this area.
