Petz recovery from subsystems in conformal field theory
Shreya Vardhan, Annie Y. Wei, Yijian Zou
We probe the multipartite entanglement structure of the vacuum state of a CFT in 1+1 dimensions, using recovery operations that attempt to reconstruct the density matrix in some re…
Channeling quantum criticality
Yijian Zou, Shengqi Sang, Timothy H. Hsieh
We analyze the effect of decoherence, modelled by local quantum channels, on quantum critical states and we find universal properties of the resulting mixed state's entanglement, b…
Universal tripartite entanglement in one-dimensional many-body systems
Yijian Zou, Karthik Siva, Tomohiro Soejima +2
Motivated by conjectures in holography relating the entanglement of purification and reflected entropy to the entanglement wedge cross-section, we introduce two related non-negativ…
Emergence of conformal symmetry in quantum spin chains: anti-periodic boundary conditions and supersymmetry
Yijian Zou, Guifre Vidal
Universal properties of a critical quantum spin chain are encoded in the underlying conformal field theory (CFT). This underlying CFT is fully characterized by its conformal data.…
Magic entanglement renormalization for quantum fields
Yijian Zou, Martin Ganahl, Guifre Vidal
Continuous tensor networks are variational wavefunctions proposed in recent years to efficiently simulate quantum field theories (QFTs). Prominent examples include the continuous m…
TensorNetwork: A Library for Physics and Machine Learning
Chase Roberts, Ashley Milsted, Martin Ganahl +6
TensorNetwork is an open source library for implementing tensor network algorithms. Tensor networks are sparse data structures originally designed for simulating quantum many-body…
