To think quantum computers at IBM in the 80's, its sad to think companies like IBM and Bell Labs are not the same companies they used to be, I mean the people working at those companies during the 20th century changed the world. Im glad they got this award as it is apparent they had a huge impact on security and quantum computing in general.
No, there is one award each year, and this year it is shared equally between two people: Charles Bennett and Gilles Brassard. This happens more often, and it has even been shared between three people (in 2002, 2007 and 2018).
