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…
Deep thermalization under charge-conserving quantum dynamics
Rui-An Chang, Harshank Shrotriya, Wen Wei Ho +1
"Deep thermalization" describes the emergence of universal wavefunction distributions in quantum many-body dynamics, appearing on a local subsystem upon measurement of its environm…
Approximate inverse measurement channel for shallow shadows
Riccardo Cioli, Elisa Ercolessi, Matteo Ippoliti +2
Classical shadows are a versatile tool to probe many-body quantum systems, consisting of a combination of randomised measurements and classical post-processing computations. In a r…
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…
