Quantum Causal Influence
Jordan Cotler, Xizhi Han, Xiao-Liang Qi +1
We introduce a framework to study the emergence of time and causal structure in quantum many-body systems. In doing so, we consider quantum states which encode spacetime dynamics,…
Space-time random tensor networks and holographic duality
Xiao-Liang Qi, Zhao Yang
In this paper we propose a space-time random tensor network approach for understanding holographic duality. Using tensor networks with random link projections, we define boundary t…
Machine Learning Spatial Geometry from Entanglement Features
Yi-Zhuang You, Zhao Yang, Xiao-Liang Qi
Motivated by the close relations of the renormalization group with both the holography duality and the deep learning, we propose that the holographic geometry can emerge from deep…
Butterfly velocity and bulk causal structure
Xiao-Liang Qi, Zhao Yang
The butterfly velocity was recently proposed as a characteristic velocity of chaos propagation in a local system. Compared to the Lieb-Robinson velocity that bounds the propagation…
Holographic coherent states from random tensor networks
Xiao-Liang Qi, Zhao Yang, Yi-Zhuang You
Random tensor networks provide useful models that incorporate various important features of holographic duality. A tensor network is usually defined for a fixed graph geometry spec…
Holographic duality from random tensor networks
Patrick Hayden, Sepehr Nezami, Xiao-Liang Qi +3
Tensor networks provide a natural framework for exploring holographic duality because they obey entanglement area laws. They have been used to construct explicit toy models realizi…
Bidirectional holographic codes and sub-AdS locality
Zhao Yang, Patrick Hayden, Xiao-Liang Qi
Tensor networks implementing quantum error correcting codes have recently been used to construct toy models of holographic duality explicitly realizing some of the more puzzling fe…
