Quantum resource localizability transitions in deep thermalization
Xiaozhou Feng, Chang Liu, Zihan Cheng +2
We investigate how quantum resource constraints affect deep thermalization, the emergence of universal local wavefunction distributions from partial measurements of a quantum many-…
Hardness of observing strong-to-weak symmetry breaking
Xiaozhou Feng, Zihan Cheng, Matteo Ippoliti
Spontaneous symmetry breaking (SSB) is the cornerstone of our understanding of quantum phases of matter. Recent works have generalized this concept to the domain of mixed states in…
Postselection-free experimental observation of the measurement-induced phase transition in circuits with universal gates
Xiaozhou Feng, Jeremy Côté, Stefanos Kourtis +1
Monitored many-body systems can exhibit a phase transition between entangling and disentangling dynamical phases by tuning the strength of measurements made on the system as it evo…
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…
