It's Spring time, when young SF fans' fancies turn to spending 4 days in panels vaguely related to their topics, if not to SF, and so this year we came again to the Radisson Non-Euclidean Hotel, just off Heathrow Starport. Its topology remains as bewildering as ever, with non-contiguous floor numbering and parts of the fourth floor not path-connected, so geodesics need to be extra-dimensional. No wonder the first sign posters trying to make navigation easier were never seen again.
But now they've added quantum light switching, so one day a switch controls the bathroom light, and the next it does nothing, but another (doubtless entangled with the same qubit) switch takes over. Obviously this is far more convenient than the Classical Electronics system of having wires between switches and lights. Probably.( Collapse )
