Pseudoentanglement from tensor networks
Zihan Cheng, Xiaozhou Feng, Matteo Ippoliti
Pseudoentangled states are defined by their ability to hide their entanglement structure: they are indistinguishable from random states to any observer with polynomial resources, y…
Holographic Classical Shadow Tomography
Shuhan Zhang, Xiaozhou Feng, Matteo Ippoliti +1
We introduce "holographic shadows", a new class of randomized measurement schemes for classical shadow tomography that achieves the optimal scaling of sample complexity for learnin…
Charge and Spin Sharpening Transitions on Dynamical Quantum Trees
Xiaozhou Feng, Nadezhda Fishchenko, Sarang Gopalakrishnan +1
The dynamics of monitored systems can exhibit a measurement-induced phase transition (MIPT) between entangling and disentangling phases, tuned by the measurement rate. When the dyn…
Dynamics of Pseudoentanglement
Xiaozhou Feng, Matteo Ippoliti
The dynamics of quantum entanglement plays a central role in explaining the emergence of thermal equilibrium in isolated many-body systems. However, entanglement is notoriously har…
