2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/91093To celebrate the 60th birthday of Charles H.Bennett I (1) publicly announce my referee reports for the original dense coding and teleportation papers, (2) present a very economical solution to the Bernstein-Vazirani problem that does not even hint at interference between multiple universes, and (3) describe how I inadvertently reinvented the Copenhagen interpretation in the course of constructing a simple, straightforward, and transparent introduction to quantum mechanics for computer scientists.15 pages. Based on my talk at the Charles H. Bennett 60th Birthday Symposium, 8-9 May, 2003. Submitted to IBM Journal of Research and DevelopmentQuantum Physicstext
