报告：In my lecture I will explain the basis behind the relationship between

thermodynamics and (quantum) information theory. I will show how our

information about the system we are manipulating allows us to extract

work from it. I will then discuss some basic results relating information

to thermodynamical work and illustrate this using the concept of

Maxwell's demon. Finally, I will present a quantum optical experiment

where a simple photon subtraction process is used to gain information

about the state of light which is then fed forward to extract electrostatic

work from a capacitor. Understanding whether quantum physics offers

any thermodynamical advantages presents one of the main open

questions in this exciting field.

报告人：Prof. Vlatko Vedral is a professor of quantum information theory at the

University of Oxford and professor of physics at the National University of

Singapore (where he is a PI at the Centre for Quantum Technologies). He is

currently a Chair Professor at the IIIS at Tsinghua. He is the Director of the

Oxford Martin School institute on “bio-inspired quantum technologies”. This

explores the exciting possibility that living systems are subject to useful

quantum effects, with a view to deriving and reverse-engineering

architectures to inspire future quantum technologies that will help address

serious challenges facing humanity in the 21st century. He has received

numerous awards in recognition for his contribution to the development of

the field, including the Royal Society Wolfson Research Merit Award and the

World Scientific Medal and Prize. He has over 260 publications on quantum

physics and collaborates in many inter-disciplinary international networks.。
