This year in Växjö we thought we would try an experiment—it felt high timefor a new result. Much of the foundations discussion ofprevious years has focussed on EPR-style arguments and the meaningand experimental validity of various Bell inequality violations. Yet, thereis another pillar of the quantum foundations puzzle that hashardly received any attention in our great series of meetings:It is the phenomenon first demonstrated by Kochen and Specker,quantum contextuality. Recently there has been a rapid growth ofactivity aimed toward better understanding this aspect of quantum mechanics,which Asher Peres sloganized by the phrase, “unperformed experiments haveno results.” Below is a sampling of some important paperson the topic for the reader not yet familiar withthe subject. What is the source of this phenomenon? Doesit depend only on high level features of quantum mechanics,or is it deep in the conceptual framework on whichthe theory rests? Might it, for instance, arise from theway quantum mechanics amends the classic laws of probability? Whatare the mathematically simplest ways contextuality can be demonstrated? Howmight the known results be made amenable to experimental tests?These were the sorts of discussions we hoped the sessionwould foster.
