Title: Categorification and Contact Non-squeezing.

**Abstract:**

**
In this talk we will discuss the contact non-squeezing problem in the ambient pre-quantization space. The problem is rooted in pure symplectic and contact topology. However, we will provide a specific approach from the mixed viewpoints of operator valued measurement, categorification, and homological algebra of derived category.
