A Century of Quantum Physics: Quantum Computing, Teleportation and Other Surprises
Abstract:
It is now 100 years since the birth of quantum physics and the centennial is being celebrated worldwide in the United Nations International Year of Quantum Science and Technology. Another amazing achievement of the 20th century was the creation of Computer Science and associated information technologies. Both have been immensely transformative for our daily lives and in the 1980s it was realised that their union has a remarkable special synergy -- in particular it offers novel extraordinary insights and benefits for many issues of computing, communication and information security, as well as a deepened understanding of the enigma that is physical reality itself. In this talk we will give an accessible introduction to the basis of quantum theory and outline some of its extraordinary benefits for information technology, including the possibility of exponentially enhanced computing power and the protocol called quantum teleportation.

Prof. Richard Jozsa FRS
Emeritus Leigh Trapnell Professor of Quantum Physics, University of Cambridge
Richard Jozsa FRS is Emeritus Leigh Trapnell Professor of Quantum Physics at the University of Cambridge UK, and former Head of the Cambridge Centre for Quantum Information and Foundations. He is widely regarded as one of the founders of the field of Quantum Computing. With Deutsch he gave the first example of a quantum algorithm having a provable exponential benefit over classical computing; and he is a co-discoverer of the process of quantum teleportation. With Schumacher and others, he developed the seminal quantum source coding theorem and further properties of the new concept of quantum information. In 2019 he was elected a Fellow of the Royal Society, the oldest continuously existing scientific academy in the world, formerly headed by Isaac Newton.
