Next Wednesday, I will be giving an invited lecture at the National Cheng Kung University in Tainan, Taiwan, about all that I’ve learnt concerning the information-disturbance tradeoff in quantum theory. Keeping a unified viewpoint, I will cover many aspects of the problem: from the difference between physical and stochastic reversibility, to qualitative “no information without disturbance” statements and quantitative balance equations, up to the two-observable approach à la Heisenberg.
