Zhongdong Liu

Hello! I’m Zhongdong Liu (刘中东). I’m currently a Software Engineer at Meta, where I work on datacenter design and configuration. Feel free to reach out if you’d like to connect or have any questions.

I received my Ph.D. in Computer Science from Virginia Tech, where I was fortunate to be advised by Dr.Bo Ji. My research interests lie in the modeling, analysis, control, optimization, and learning of computer and network systems, with a particular focus on information-update systems.

Before joining Virginia Tech, I earned my B.S. degree in Mathematics (with Honors) from Northeast Forestry University, Harbin, China, in 2016.

In a complete theory there is an element corresponding to each element of reality. A sufficient condition for the reality of a physical quantity is the possibility of predicting it with certainty, without disturbing the system. In quantum mechanics in the case of two physical quantities described by non-commuting operators, the knowledge of one precludes the knowledge of the other. Then either (1) the description of reality given by the wave function in quantum mechanics is not complete or (2) these two quantities cannot have simultaneous reality. Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that if (1) is false then (2) is also false. One is thus led to conclude that the description of reality as given by a wave function is not complete.
