Quantum Chaos and Physical Distance Between Quantum States
内容： It has been long argued and accepted that there is no true quantum chaos due to the linearity of the Schrödinger equation. Berry even suggested to change quantum chaos, a confusing oxymoron, to...

Quantum noise effects and quantum error mitigation
内容： In this talk, I plan to introduce our two recent works (arXiv: 2201.00752, arXiv: 2207.01403). I will begin with briefly introducing the basic concepts of quantum error mitigation (QEM) in the ...
