In this seminar, I will explain the working principles of quantum key distribution (BB84 & Ekert 91 protocols), quantum repeater (entanglement swapping, entanglement purification & quantum memory), Bell state measurement, quantum teleportation and also its recent experimental progresses.


Yisheng got his bachelor's degree in physics from Nanyang Technological University, Singapore, advised by Prof. Rainer Dumke. He joined Purdue Department of Physics & Astronomy as a PhD student in January 2021. He is currently working in Prof. Mahdi Hosseini's lab to build quantum memories. He was the CEO & Co-founder of INNOTUS in Singapore.
