At the occasion of the 10th aniversary of ZX calculus for quantum foundation/computing, the recent wave of exciting results concerning both for its theoretical underpinning and new applications for quantum computing, as well as the simple fact that there never can be enough parties, there will be a celebratory workshop in Oxford, at a location still to be confirmed. The main goal of the workshop is to set out and coordinate further developments. At the same time, this would be a good occasion for those that would like to learn more about ZX calculus to talk to those that have made major contributions. Live music will also be provided, most likely on the eve of the 11th. If you are interested in participating send us an email. Dates: 7-11 May 2018. Place: Oxford, at location TBC. Confirmed participants include: Bob Coecke, Ross Duncan, Dusko Pavlovic, Simon Perdrix, Aleks Kissinger, Dominic Horsman, Miriam Backens, Amar Hadzihasanovic, Vladimir Zamdzhiev, Stefano Gogioso, Quanlong Wang, Renaud Vilmart, Kang Feng Ng, Hector Miller-Bakewel, Niel De Beaudrap, Giovanni De Felice and Cambridge Quantum Computing Inc. representatives.
