Iridium Point Goes to 1st International Symposium on Quantum Computing and Musical Creativity
Well, Y. F. Wang, PhD student at the Auckland U’s physics department is going. I don’t think my (computational) musical misadventures deserve any recognitions yet. This Event is hosted by University of Plymouth in late November, and features many downstream Quantum info professionals at places such as Cambridge Quantum Computing Lab and IBM. My notes … Continue reading Iridium Point Goes to 1st International Symposium on Quantum Computing and Musical Creativity
